Aaron Durbin de1f890186 coreboot: add caching loaded ramstage interface
Instead of hard coding the policy for how a relocated ramstage
image is saved add an interface. The interface consists of two
functions.  cache_loaded_ramstage() and load_cached_ramstage()
are the functions to cache and load the relocated ramstage,
respectively. There are default implementations which cache and
load the relocated ramstage just below where the ramstage runs.

Aaron Durbin 8ce667e506 haswell: add multipurpose SMM memory region
The SMM region is available for multipurpose use before the SMM
handler is relocated. Provide a configurable sized region in the
TSEG for use before the SMM handler is relocated. This feature is
implemented by making the reserved size a Kconfig option. Also
make the IED region a Kconfig option as well. Lastly add some sanity
checking on the Kconfig options.

Aaron Durbin 738af675d1 haswell: support for parallel SMM relocation
The haswell processors support the ability to save their SMM state
into MSR space instead of the memory. This feaure allows for parallel
SMM relocation handlers as well as setting the same SMBASE for each
CPU since the save state memory area is not used.

The catch is that in order determine if this feature is available the
CPU needs to be in SMM context. In order to implement parallel SMM
relocation the BSP enters the relocation handler twice. The first time
is to determine if that feature is available. If it is, then that
feature is enabled the BSP exits the relocation handler without
relocating SMBASE. It then releases the APs to run the SMM relocation
handler. After the APs have completed the relocation the BSP will
re-enter the SMM relocation handler to relocate its own SMBASE to the
final location.  If the parallel SMM feature is not available the BSP
relocates its SMBASE as it did before.

This change also introduces the BSP waiting for the APs to relocate
their SMBASE before proceeding with the remainder of the boot process.

Ensured both the parallel path and the serial path still continue
to work on cold, warm, and S3 resume paths.

Aaron Durbin 159f2ef03a ramstage: cache relocated ramstage in RAM
Accessing the flash part where the ramstage resides can be slow
when loading it. In order to save time in the S3 resume path a copy
of the relocated ramstage is saved just below the location the ramstage
was loaded. Then on S3 resume the cached version of the relocated
ramstage is copied back to the loaded address.

This is achieved by saving the ramstage entry point in the
romstage_handoff structure as reserving double the amount of memory
required for ramstage. This approach saves the engineering time to make
the ramstage reentrant.

The fast path in this change will only be taken when the chipset's
romstage code properly initializes the s3_resume field in the
romstage_handoff structure. If that is never set up properly then the
fast path will never be taken.

e820 entries from Linux:
BIOS-e820: [mem 0x000000007bf21000-0x000000007bfbafff] reserved
BIOS-e820: [mem 0x000000007bfbb000-0x000000007bffffff] type 16

The type 16 is the cbmem table and the reserved section contains the two
copies of the ramstage; one has been executed already and one is
the cached relocated program.

With this change the S3 resume path on the basking ridge CRB shows
to be ~200ms to hand off to the kernel:

13 entries total:

   1:95,965
   2:97,191 (1,225)

Provide a field in the romstage_handoff structure to indicate if the
current boot is an ACPI S3 wake boot. There are currently quite a few
non-standardized ways of passing this knowledge to ramstage from

passing along this information. However, it still requires the romstage
chipset code to initialize this field. In short, this change does not
make this a hard requirement for ramstage.

calling convention.

2. Pick the proper stack to use after cache-as-ram is torn down. When
   the ramstage is relocatable, finding a stack to use before vectoring
   into ramstage is impossible since the ramstage is a black box with an
   unknown layout.

Aaron Durbin 8e4a355773 coreboot: introduce CONFIG_RELOCATABLE_RAMSTAGE
This patch adds an option to build the ramstage as a reloctable binary.
It uses the rmodule library for the relocation. The main changes
consist of the following:

1. The ramstage is loaded just under the cmbem space.
2. Payloads cannot be loaded over where ramstage is loaded. If a payload
   is attempted to load where the relocatable ramstage resides the load
   is aborted.
3. The memory occupied by the ramstage is reserved from the OS's usage
   using the romstage_handoff structure stored in cbmem. This region is
   communicated to ramstage by an CBMEM_ID_ROMSTAGE_INFO entry in cbmem.
4. There is no need to reserve cbmem space for the OS controlled memory for
   the resume path because the ramsage region has been reserved in #3.
5. Since no memory needs to be preserved in the wake path, the loading
   and begin of execution of a elf payload is straight forward.

ramstage to communicate with one another instead of using sideband
signals such as stuffing magic values in pci config or memory
scratch space. Initially this structure just contains a single region
that indicates to ramstage that it should reserve a memory region used
by the romstage. Ramstage looks for a romstage_handoff structure in cbmem
with an id of CBMEM_ID_ROMSTAGE_INFO. If found, it will honor reserving
the region defined in the romstage_handoff structure.

Aaron Durbin a146d58ca0 ramstage: prepare for relocation
The current ramstage code contains uses of symbols that cause issues
when the ramstage is relocatable. There are 2 scenarios resolved by this
patch:

1. Absolute symbols that are actually sizes/limits. The symbols are
   problematic when relocating a program because there is no way to
   distinguish a symbol that shouldn't be relocated and one that can.
   The only way to handle these symbols is to write a program to post
   process the relocations and keep a whitelist of ones that shouldn't
   be relocated. I don't believe that is a route that should be taken
   so fix the users of these sizes/limits encoded as absolute symbols
   to calculate the size at runtime or dereference a variable in memory
   containing the size/limit.

2. Absoulte symbols that were relocated to a fixed address. These
   absolute symbols are generated by assembly files to be placed at a
   fixed location. Again, these symbols are problematic because one
   can't distinguish a symbol that can't be relocated. The symbols
   are again resolved at runtime to allow for proper relocation.

For the symbols defining a size either use 2 symbols and calculate the
difference or provide a variable in memory containing the size.

Ronald G. Minnich a95a13bd47 link/graphics: New state machine
This is a new state machine. It is more programmatic, in the
case of auxio, and has much more symbolic naming, and very few
"magic" numbers, except in the case of undocumented settings.

As before, the 'pre-computed' IO ops are encoded in the iodefs
table. A function, run, is passed and index into the table and
runs the ops.

A new operator, I, has been added. When the I operator is hit,
run() returns the index of the next operator in the table.

The i915lightup function runs the table. All the AUX channel ops
have been removed from the table, however, and are now called as
functions, using the previously committed auxio function.

The iodefs table has been grouped into blocks of ops, which end in
an I operator. As the lightup function progresses through startup,
and the run() returns, the lightup function performs aux channel
operations.

This code is symbolic enough, I hope, that it will make haswell
graphics bringup simpler.

i915io.c, and the core of the code in i915lightup.c, were
programatically generated, starting with IO logs from the DRM
startup code in the kernel. It is possible to apply the tools that
do this generation to newer IO logs from the kernel.

David Hendricks bba8090421 armv7/exynos/snow: new cache maintenance API
This adds a new API for cache maintenance operations. The idea is
to be more explicit about operations that are going on so it's easier
to manage branch predictor, cache, and TLB cleans and invalidations.

Also, this adds some operations that were missing but required early
on, such as branch predictor invalidation. Instruction and sync
barriers were wrong earlier as well since the imported API assumed
we compield with -march=armv5 (which we don't) and was missing
wrappers for the native ARMv7 ISB/DSB/DMB instructions.

For now, this is a start and it gives us something we can easily use
in libpayload for doing things like cleaning and invalidating dcache
when doing DMA transfers.

TODO:
- Set cache policy explicitly before re-enabling. Right now it's left
  at default.
- Finish deprecating old cache maintenance API.
- We do an extra icache/dcache flush when going from bootblock to
  romstage.

Aaron Durbin 94998c4d3f lynxpoint: Add cbfs_load_payload() implementation
SPI accesses can be slow depending on the setup and the access pattern.
The current SPI hardware setup to cache and prefetch. The alternative
cbfs_load_payload() function takes advantage of the caching in the CPU
because the ROM is cached as write protected as well as the SPI's
hardware's caching/prefetching implementation. The CPU will fetch
consecutive aligned cachelines which will hit the ROM as
cacheline-aligned addresses. Once the payload is mirrored into RAM the
segment loading can take place by reading RAM instead of ROM.

With the alternative cbfs_load_payload() the boot time on a baskingridge
board saves ~100ms. This savings is observed using cbmem.py after
performing warm reboots and looking at TS_SELFBOOT_JUMP (99) entries.
This is booting with a depthcharge payload whose payload file fits
within the SMM_DEFAULT_SIZE (0x10000 bytes).

Datapoints with TS_LOAD_PAYLOAD (90) & TS_SELFBOOT_JUMP (99) cbmem entries:

Aaron Durbin 633f11274f x86: remove stack definition in linker script
In order to prepare the ramstage to be linked by the rmodule linker the
stack needs to be self-contained within the ramstage objects. The
reasoning is that the rmodule linker provides a way to define a heap,
but it doesn't currently have a region for the stack.

The downside to this is that memory footprint of the ramstage can change
when compared before this change. The size difference stems from the
link ordering of the objects as the stack is now defined within
c_start.S. The size fluctuation ranges from 0 to CONFIG_STACK_SIZE - 1
because of the previous behavior or aligning to CONFIG_STACK_SIZE. It
should be noted that such an alignment is unnecessary for 32-bit x86 as
the alignment requirement for the stacks are 4 byte alignment. Also the
memory footprint is still dominated by CONFIG_RAMTOP and CONFIG_RAMBASE.

Kimarie Hoot fa91819e89 AMD Fam15: Add SPD read functions to wrapper code
Change:
This is the initial step for moving the AMD F15 & HUDSON1,2,3
SPD-read callout out of the mainboard directories and into
the wrapper.  The next step is to update the platforms to use
this routine in BiosCallouts.c and to delete the code from the
mainboard directories.  The DIMM addresses should be moved into
devicetree.cb.
If there are significant differences or reasons that the mainboard
needs to override this code, it's perfectly reasonable to keep using
the version in the mainboard, but this allows us to remove duplicated
code and simplify the mainboard directories.

Notes:
This started by duplicating what was in Dinar, and was changed to
use the devicetree.cb structures.  Significant cleanup and magic
number reduction was done as well.

It is intended that this file will not be included in ramstage as
the DIMM init is all done in romstage.

This is similar to what was done for Parmer/Thatcher in commit
7fb692bd - http://review.coreboot.org/#/c/2190/

cbfstool usage change:
   The "-a" parameter for "cbfstool locate" is switched to "-P/--page-size".

The "locate" command was used to find a place to store ELF stage image in one
memory page. Its argument "-a (alignment)" was actually specifying the page size
instead of doing memory address alignment. This can be confusing when people are
trying to put a blob in aligned location (ex, microcode needs to be aligned in
0x10), and see this:
  cbfstool coreboot.rom locate -f test.bin -n test -a 0x40000
  # output: 0x44, which does not look like aligned to 0x40000.

To prevent confusion, it's now switched to "-P/--page-size".

Verified by building i386/axus/tc320 (with page limitation 0x40000):

Aaron Durbin 305b1f0d30 haswell: Parallel AP bringup
This patch parallelizes the AP startup for Haswell-based devices. It
does not touch the generic secondary startup code. Instead it provides
its own MP support matching up with the Haswell BWG. It seemed to be too
much trouble to support the old startup way and this new way. Because of
that parallel loading is the only thing supported.

A couple of things to note:
1. Micrcode needs to be loaded twice. Once before MTRR and caching is
   enabled. And a second time after SMM relocation.
2. The sipi_vector is entirely self-contained. Once it is loaded and
   written back to RAM the APs do not access memory outside of the
   sipi_vector load location until a sync up in ramstage.
3. SMM relocation is kicked off by an IPI to self w/ SMI set as the
   destination mode.

The following are timings from cbmem with dev mode disabled and recovery mode
enabled to boot directly into the kernel. This was done on the
baskingridge CRB with a 4-core 8-thread CPU and 2 DIMMs 1GiB each. The
kernel has console enabled on the serial port. Entry 70 is the device
initialization, and that is where the APs are brought up. With these two
examples it looks to shave off ~200 ms of boot time.

Aaron Durbin 98ffb426f4 intel microcode: split up microcode loading stages
This patch only applies to CONFIG_MICROCODE_IN_CBFS. The intel microcode
update routine would always walk the CBFS for the microcode file. Then
it would loop through the whole file looking for a match then load the
microcode. This process was maintained for intel_update_microcode_from_cbfs(),
however 2 new functions were exported:
	1.  const void *intel_microcode_find(void)
	2.  void intel_microcode_load_unlocked(const void *microcode_patch)

The first locates a matching microcode while the second loads that
mircocode. These new functions can then be used to cache the found
microcode blob w/o having to re-walk the CBFS.

Booted baskingridge board to Linux and noted that all microcode
revisions match on all the CPUs.

Having this header file in the mainboard directory breaks
the dinar build on cygwin because the header file in the

src/vendorcode/amd/cimx/sb700/OEM.h.  The build probably works
fine on Linux systems because, due to case-sensitivity, Oem.h
will not match the #include "OEM.h" statement in

The Oem.h file in the dinar mainboard is not used by any other
source files, and the defines in the dinar mainboard are duplicated
by defines in the correct OEM.h file.  Therefore, the file can be
safely removed.

The save_mrc_data() was previously called conditionally
in the raminit code. The save_mrc_data() function was called
in the non-S3 wake paths. However, the common romstage_common()
code was checking cbmem initialization things on s3 wake. Between
the two callers cbmem_initialize() was being called twice in the
non-s3 wake paths.  Moreover, saving of the mrc data was not allowed
when CONFIG_EARLY_CBMEM_INIT wasn't enabled.

Therefore, move the save_mrc_data() to romstage_common. It already has
the knowledge of the wake path. Also remove the CONFIG_EARLY_CBMEM_INIT
requirement from save_mrc_data() as well as the call to cbmem_initialize().

This commit pulls in all the common logic for romstage into

still reside under their respective directories. The calling
sequence bounces from the cpu directory to mainboard then back
to the cpu directory. The reasoning is that Haswell systems use
cache-as-ram for backing memory in romstage. The stack is used to
allocate structures. However, now changes can be made to the
romstage for Haswell and apply to all boards.

Aaron Durbin 3d0071bde3 haswell: adjust CAR usage
It was found that the Haswell reference code was smashing through the
stack into the reference code's heap implementation. The reason for this
is because our current CAR allocation is too small. Moreover there are
quite a few things to coordinate between 2 code bases to get correct.
This commit separates the CAR into 2 parts:
  1. MRC CAR usage.
  2. Coreboot CAR usage.
Pointers from one region can be passed between the 2 modules, but one
should not be able to affect the others as checking has been put into
place in both modules.

The CAR size has effectively been doubled from 0x20000 (128 KiB) to
0x40000 (256KiB). Not all of that increase was needed, but enforcing
a power of 2 size only utilizes 1 MTRR.

Old CAR layout with a single contiguous stack with the region starting
at CONFIG_DCACHE_RAM_BASE:

+---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE
|  MRC global variables                 |
|  CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes |
+---------------------------------------+
|  ROM stage stack                      |
|                                       |
|                                       |
+---------------------------------------+
|  MRC Heap 30000 bytes                 |
+---------------------------------------+
|  ROM stage console                    |
|  CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes |
+---------------------------------------+
|  ROM stage CAR_GLOBAL variables       |
+---------------------------------------+ Offset 0

There was some hard coded offsets in the reference code wrapper to start
the heap past the console buffer. Even with this commit the console
can smash into the following region depending on what size
CONFIG_CONSOLE_CAR_BUFFER_SIZE is.

As noted above This change splits the CAR region into 2 parts starting
at CONFIG_DCACHE_RAM_BASE:

+---------------------------------------+
|  MRC Region                           |
|  CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes |
+---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE
|  ROM stage stack                      |
|                                       |
|                                       |
+---------------------------------------+
|  ROM stage console                    |
|  CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes |
+---------------------------------------+
|  ROM stage CAR_GLOBAL variables       |
+---------------------------------------+ Offset 0

Another variable was add, CONFIG_DCACHE_RAM_ROMSTAGE_STACK_SIZE,
which represents the expected stack usage for the romstage. A marker
is checked at the base of the stack to determine if either the stack
was smashed or the console encroached on the stack.

Aaron Durbin ad93552b86 lib: add rmodule support
A rmodule is short for relocation module. Relocaiton modules are
standalone programs. These programs are linked at address 0 as a shared
object with a special linker script that maintains the relocation
entries for the object. These modules can then be embedded as a raw
binary (objcopy -O binary) to be loaded at any location desired.

Initially, the only arch support is for x86. All comments below apply to
x86 specific properties.

The intial user of this support would be for SMM handlers since those
handlers sometimes need to be located at a dynamic address (e.g. TSEG
region).

The relocation entries are currently Elf32_Rel. They are 8 bytes large,
and the entries are not necessarily in sorted order. An future
optimization would be to have a tool convert the unsorted relocations
into just sorted offsets. This would reduce the size of the blob
produced after being processed. Essentialy, 8 bytes per relocation meta
entry would reduce to 4 bytes.

Aaron Durbin 7af20698f6 haswell: enable caching before SMM initialization
The SMM handler resides in the TSEG region which is far above
CONFIG_RAM_TOP (which is the highest cacheable address) before
MTRRs are setup. This means that calling initialize_cpus() before
performing MTRR setup on the BSP means the SMM handler is copied
using uncacheable accesses.

Improve the SMM handler setup path by enabling performing MTRR setup on
for the BSP before the call to initialize_cpus(). In order to do this
the haswell_init() function was split into 2 paths: BSP & AP paths.
There is a cpu_common_init() that both call to perform similar
functionality. The BSP path in haswell_init() then starts the APs using
intel_cores_init(). The AP path in haswell_init() loads microcode and
sets up MTRRs.

This split will be leveraged for future support of bringing up APs in
parallel as well as adhering to the Haswell MP initialization
requirements.

There was a mix of setup code sprinkled across the various components:
southbridge code in the northbridge, etc. This commit reorganizes the
code so that northbridge code doesn't initialize southbridge components.
Additionally, the calling dram initialization no longer calls out to ME
code. The main() function in the mainboard calls the necessary ME
functions before and after dram initialization.

The biggest change is the addition of an early_pch_init() function
which initializes the BARs, GPIOs, and RCBA configuration. It is also
responsible for reporting back to the caller if the board is being
woken up from S3. The one sequence difference is that the RCBA config
is performed before claling the reference code.

Lastly the rcba configuration was changed to be table driven so that
different board/configurations can use the same code. It should be
possible to have board/configuration specific gpio and rcba
configuration while reusing the romstage code.

objcopy -B provides symbols of the form _binary_<name>_(start|end|size).
However, the _size variant is an absoult symbol.  If one wants to
relocate the smi loading the _size symbol will be relocated which is
wrong since it is suppose to be a fixed size. There is no way to
distinguish symbols that shouldn't be relocated vs ones that can.
Instead use the _start and _end variants to determine the size.

Aaron Durbin e6c3b1d30d haswell: include TSEG region in cacheable memory
The SMRR takes precedence over the MTRR entries. Therefore, if the TSEG
region is setup as cacheable through the MTTRs, accesses to the TSEG
region before SMM relocation are cached. This allows for the setup of
SMM relocation to be faster by caching accesses to the future TSEG
(SMRAM) memory.

Mike Loptien 594ea4ac5f ASROCK Fam14 DSDT: Add secondary bus range to PCI0
Adding the 'WordBusNumber' macro to the PCI0
CRES ResourceTemplate in the Persimmon DSDT.
This sets up the bus number for the PCI0 device
and the secondary bus number in the CRS method.
This change came in response to a 'dmesg' error
which states:
'[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS'

By adding the 'WordBusNumber' macro, ACPI can set
up a valid range for the PCIe downstream busses,
thereby relieving the Linux kernel from "guessing"
the valid range based off _BBN or assuming [0-0xFF].
The Linux kernel code that checks this bus range is
in `drivers/acpi/pci_root.c`.  PCI busses can have
up to 256 secondary busses connected to them via
a PCI-PCI bridge.  However, these busses do not
have to be sequentially numbered, so leaving out a
section of the range (eg. allowing [0-0x7F]) will
unnecessarily restrict the downstream busses.

I am removing the _INI method from the AZHD device because
it does not seem to do anything and causes errors in the

method performs device specific initialization and is
run when OSPM loads a description table.  It must only

_REG method and during my testing, I added a REG method
but it did not seem to make a difference in the PCI
register space.  The bit fields defined as NSDI (Disable
No Snoop), NSDO (Disable No Snoop Override), and NSEN
(Enable No Snoop Request) do not ever get written from
their default values.  And writing to these bit fields
does not seem to be necessary because I did not notice
any change in audio functionality.

In an effort to clean up as many FWTS errors as possible,
I propose removing this method altogether.  I have seen no
change in operation (audio works with and without this
method) and there does not seem to be any change in lspci
or dmesg.

it in a way compatible with upstream coreboot.

1. Add options to src/device/Kconfig to enable native graphics.
2. Export the MTRR function for setting variable MTRRs.
3. Clean up some of the comments and white space.

While I realize that the product name is Pixel, the mainboard in the

Mike Loptien 8d629c14eb Persimmon DSDT: Remove INI method from AZHD device
I am removing the _INI method from the AZHD device because
it does not seem to do anything and causes errors in the
FWTS[1] (Firmware Test Suite) test 'method'. The INI
method performs device specific initialization and is
run when OSPM loads a description table.  It must only
access OperationRegions that have been indicated as
available by the _REG (Region) method.  We do not have a
_REG method and during my testing, I added a REG method
but it did not seem to make a difference in the PCI
register space.  The bit fields defined as NSDI (Disable
No Snoop), NSDO (Disable No Snoop Override), and NSEN
(Enable No Snoop Request) do not ever get written from
their default values.  And writing to these bit fields
does not seem to be necessary because I did not notice
any change in audio functionality.

In an effort to clean up as many FWTS errors as possible,
I propose removing this method altogether.  I have seen no
change in operation (audio works with and without this
method) and there does not seem to be any change in lspci
or dmesg.

FWTS information can be found here:

Mike Loptien e31c0ed9b5 Persimmon DSDT: Add OSC method
The _OSC method is used to tell the OS what capabilities
it can take control over from the firmware.  This method
is described in chapter 6.2.9 of the ACPI spec v3.0.
The method takes 4 inputs (UUID, Rev ID, Input Count,
and Capabilities Buffer) and returns a Capabilites
Buffer the same size as the input Buffer.  This Buffer
is generally 3 Dwords long consisting of an Errors
Dword, a Supported Capabilities Dword, and a Control
Dword.  The OS will request control of certain
capabilities and the firmware must grant or deny control
of those features.  We do not want to have control over
anything so let the OS control as much as it can.

The _OSC method is required for PCIe devices and dmesg
checks for its existence and issues an error if it is
not found.

Aaron Durbin 1fef1f5177 haswell: reserve default SMRAM space
Currently the OS is free to use the memory located at the default
SMRAM space because it is not marked reserved in the e820. This can
lead to memory corruption on S3 resume because SMM setup doesn't save
this range before using it to relocate SMRAM.

Aaron Durbin c12ef9723e haswell: resource allocation
The previous code w.r.t. resource allocation was getting lucky
based on the way fixed mmio resources on the system were being
chosen. Namely, PCIEXBAR was the lowest mmio space and the other
fixed non-standar BARs were above it. The resource allocator would
then start allocating standard BARs below that.

On top of that other resources were being added when
dev_ops->set_resources() was being called on the PCI domain. At that
point the PCI range limit were already picked for where to start
allocating from.

To ensure we no longer get lucky during resource allocation add the
fixed resources in the host bridge and add the memory controller
cacheable memory areas. With those resources added the range limit
for standard PCI BARs is chosen properly.

Depending on haswell board configurations we may need to adjust and
pass in the size of physical address space needed for PCI resources
to the reference code. For the time being the CRBs appear to be OK.

Lastly, remove the SNB workaround for reserving 2MiB at 1GiB and 512MiB.

Aaron Durbin 6f561afa4a lynxpoint: lpc resource reservations
This commit updates the Lynx Point resource reservations before
the coreboot allocator assigns resources. There is no need to mark
anything as subtractive decode because there are no devices/buses
linked to the LPC device.

The I/O range reservations consists of claiming the first 4KiB
of I/O space. The PMBASE, GPIOBASE, and LPC generic I/O decode
ranges are checked against the default claimed range. If those
ranges overlap or fall outside of the default range then those
resources are added.

The MMIO range reservations consist of claiming everything from
the I/O APIC to 4GiB. The RCBA and the LPC Generic Memory range
register are then conditionally added if they fall outside of
the default MMIO range.

Christian Gmeiner 4412bc4ae8 OT200: reset MFGTP7 (backlight pwm)
The CS5536 companion device has three different power domains.
* working domain
* standby domain
* RTC domain

When the system is "off" only the standby domain is powered.
MFGPT[7:6] are member of the standby power domain.

MFGPT7 is used to control the backlight of the device and so the
timer gets used and configured during system boot. If the system
does a reboot the timer stays configured and the Linux driver
can not use it:
   "ot200-backlight: ot200-backlight.0: MFGPT 7 not availale"

The cs5535-mfgpt has a function to hard-reset all MFGPTs but the
system hangs after the first access to a MFGPT register - cause
unknown.

/*
 * This is a sledgehammer that resets all MFGPT timers. This is required by
 * some broken BIOSes which leave the system in an unstable state
 * (TinyBIOS 0.98, for example; fixed in 0.99).  It's uncertain as to
 * whether or not this secret MSR can be used to release individual timers.
 * Jordan tells me that he and Mitch once played w/ it, but it's unclear
 * what the results of that were (and they experienced some instability).
 */
static void reset_all_timers(void)
{
	uint32_t val, dummy;

	/* The following undocumented bit resets the MFGPT timers */
	val = 0xFF; dummy = 0;
	wrmsr(MSR_MFGPT_SETUP, val, dummy);
}

After playing around with this undocumented MSR it looks like I only
need to set bit 7 to free the MFGPT7.

BTW, all MFGPT[0:5] will be reset during pll_reset().

Aaron Durbin 50a34648cd x86: SMM Module Support
Add support for SMM modules by leveraging the RMODULE lib. This allows
for easier dynamic SMM handler placement. The SMM module support
consists of a common stub which puts the executing CPU into protected
mode and calls into a pre-defined handler. This stub can then be used
for SMM relocation as well as the real SMM handler. For the relocation
one can call back into coreboot ramstage code to perform relocation in
C code.

The handler is essentially a copy of smihandler.c, but it drops the TSEG
differences. It also doesn't rely on the SMM revision as the cpu code
should know what processor it is supported.

Ideally the CONFIG_SMM_TSEG option could be removed once the existing
users of that option transitioned away from tseg_relocate() and
smi_get_tseg_base().

The generic SMI callbacks are now not marked as weak in the
declaration so that there aren't unlinked references. The handler
has default implementations of the generic SMI callbacks which are
marked as weak. If an external compilation module has a strong symbol
the linker will use that instead of the link one.

Additionally, the parameters to the generic callbacks are dropped as
they don't seem to be used directly. The SMM runtime can provide the
necessary support if needed.

The Haswell parts use a PCH code named Lynx Point (Series 8). Therefore,

This code partially gets up through the romstage just before training

Mike Loptien 7bc153c6ae Eagleheights DSDT: Grant OS control through OSC
Change the OSC method to actually grant control of
PCIe capabilities to the OS instead of granting no
control.  I believe the logic was backwards in the
original commit.  Bits should be set when granting
control and cleared when not granting control.  By
setting the return value to 0x00, we effectively
tell the OS that it cannot control any PCIe
capability.  See section 6.2.9 of the ACPI spec
version 3.0 for more information.

This edit is a duplication of the OSC method that
is in the src/southbridge/intel/bd82x6x/pch.asl

Mike Loptien 4733c647bc Persimmon DSDT: Add secondary bus range to PCI0
Adding the 'WordBusNumber' macro to the PCI0
CRES ResourceTemplate in the Persimmon DSDT.
This sets up the bus number for the PCI0 device
and the secondary bus number in the CRS method.
This change came in response to a 'dmesg' error
which states:
'[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS'

By adding the 'WordBusNumber' macro, ACPI can set
up a valid range for the PCIe downstream busses,
thereby relieving the Linux kernel from "guessing"
the valid range based off _BBN or assuming [0-0xFF].
The Linux kernel code that checks this bus range is
in `drivers/acpi/pci_root.c`.  PCI busses can have
up to 256 secondary busses connected to them via
a PCI-PCI bridge.  However, these busses do not
have to be sequentially numbered, so leaving out a
section of the range (eg. allowing [0-0x7F]) will
unnecessarily restrict the downstream busses.

This change will apply to other AMD mainboards and
will be in a different commit.

Konstantin Aladyshev 7fcbbb09fd AGESA: Fix bug in AMD_DISABLE_STACK_FAMILY_HOOK_F15
_RDMSR instruction loads the contents of a 64-bit model specific register (MSR)
specified in the ECX register into registers EDX:EAX.
The EDX register is loaded with the high-order 32 bits of the MSR
and the EAX register is loaded with the low-order 32 bits.

EDX:EAX = MSR[ECX]

So bit 49 will be contained in EDX register.

Buggy code instead of bit 49 (CombineCr0Cd) sets bit [49-32=17] (PfcStrideDis).
PfcStrideDis bit disables stride prefetch generation. This leads to memory
bandwidth loss.

_________

Supermicro H8QGI board

After applying this change i observed huge memory bandwidth increase in tests
that runs on small amount of cores. But unfortunately it doesn't affect
overall bandwidth results on 4P system with 48 cores.
So i think that in this system leading limiting factor is
AMD HT-ASSIST feature (Probe filter).

But right now it is not working. System stucks in Linux boot. I have done
some experiments and figured out that stuck happens when system have cores in
compute unit (CU) other than CU with BSC (boot strap core).
CU is two cores (primary and seconary) that shares some things (L2 cache, FPU ...)
So with probe filter i can boot Linux with one (BSC)
or two (BSC + secondary core in its CU) cores.
And with this configuration i can see memory bandwidth on 1 core (or two cores)
close to original bios.

but the SST 25VF032B datasheet allows max. 25.  Lower the speed to 22 MHz,
otherwise BIOS flashing fails.

   moved into the wrapper as a platform generic function in change
   http://review.coreboot.org/#/c/2497/
   AMD f14: Add SPD read functions to wrapper code

 - Move DIMM addresses into devicetree.cb

 - Add the ASF init that used to be in the SPD read code into
   mainboard_enable()

Notes:
 - The DIMM reads only happen in romstage, so the function is not
   available in ramstage.  Point the read-SPD callback to a generic
   function in ramstage.

Martin Roth 3b2653b1fc AMD Fam14: Add SPD read functions to wrapper code
Change:
This is the initial step for moving the AMD F14 & HUDSON1,2,3
SPD-read callout out of the mainboard directories and into
the wrapper.  The next step is to update the platforms to use
this routine in BiosCallouts.c and to delete the code from the
mainboard directories.  The DIMM addresses should be moved into
devicetree.cb.
If there are significant differences or reasons that the mainboard
needs to override this code, it's perfectly reasonable to keep using
the version in the mainboard, but this allows us to remove duplicated
code and simplify the mainboard directories.

Notes:
This started by duplicating what was in Persimmon, and was changed to
use the devicetree.cb structures.  The ASF setup was also removed from
the persimmon copy (PMIO writes to 0x28 & 0x29) as that's not needed
for the SPD access and doesn't make sense to initialize here.
Significant cleanup and magic number reduction was done as well.

It is intended that this file will not be included in ramstage as
the DIMM init is all done in romstage.

This is similar to what was done for Parmer/Thatcher in commit
7fb692bd - http://review.coreboot.org/#/c/2190/
Fam15tn: Move SPD read from mainboards into wrapper

Yes, it would make sense to split this into two separate files
and move the SMBUS initialization and access into the southbridge
wrapper.  Maybe that can come next.

Paul Menzel e988b515f1 ASRock E350M1: Let `BiosGnbPcieSlotReset()` return `AGESA_UNSUPPORTED`
Quoting Jens Rottmann [1]:

Nevertheless I still think this whole function is bogus for the E350M1.  The
function assumes GPIO21 is wired to reset APU PCIe lane 0+1 (PCIe x8, port 4+5
as Coreboot/AGESA calls it), GPIO25 resets lane 2 (PCIe x4) and GPIO02 lane 3.
But the E350M1 has PCIe x16 i.e. probably APU lanes 0-3 bundled, completely
different layout.  They could have chosen GPIO21 to force resets, or 25 - or
maybe 50 like on the Persimmon or any other they fancied or - and this is the
most probable - none at all.  Having BiosGnbPcieSlotReset() toggle some GPIOs
without knowing what they do on the E350M1 (if anything at all) is nonsense.
In my opinion this whole function should just "return AGESA_UNSUPPORTED" and
good riddance.

Ronald G. Minnich 6bde149d9c samsung/exynos5: add display port and framebuffer defines and initialization
These are essential functions for setting up the display port and
framebuffer, and also enable such things as aux channel
communications.  We do some very simple initialization in romstage,
mainly set a GPIO so that the graphics is powering up, but the complex
parts are done in the ramstage. This mirrors the way in which graphics
is done in the x86 size.

I've added a first pass at a real device, and put it in the mainboard
Kconfig, hoping for corrections. Because startup is so complex,
depending on device type, I've created a 'displayport' device that
removes some of the complexity and makes the flow *much* clearer.  You
can actually follow the flow by looking at the code, which is not true
on other implementations. Since display port is perhaps the main port
used on these chips, that's a reasonable compromise. All parameters of
importance are now in the device tree.

The MMC0 on google/snow can run in 8 bit mode. To simplify driver development,
we thought disabling it (using zero, which runs in 1-bit / 4-bit mode) may help.

However, after some experiments in payload drivers, setting pinmux to 8 bit mode
can still allow MMC to run in 1-bit / 4-bit mode, so it's pretty safe to enable
8 bit mode by default for better performance.

Verified to boot on google/snow, and got MMC0 working.

Jens Rottmann 3914a316c3 AMD SB800: don't switch clock from 14 to 48 MHz for smscsuperio
The power up default for the 14M_25M_48M_OSC switchable clock output ball of
the SB800 chipset is 14 MHz.  sb800/bootblock.c changes this to 48 MHz,
which is the correct value for almost all SIOs.  However, not for
'smscsuperio' (SMSC SCH311x), which needs the original 14 MHz and is not
configurable for other clock speeds.  A wrong SIO clock supply results in
funny RS232 output (wrong bit speed) and non-working PS/2.

We could switch back to 14 MHz in the mainboard's romstage.c, but then the
clock frequency would change twice.  The resulting short 48 MHz burst causes
a handful of rubbish characters on RS232 on every boot until the SIO clock
has stabilized again.

This patch skips the SB800 clock switch if the SIO Kconfig requests 14 MHz.
This does not affect any boards currently in the repository (yet).

Jens Rottmann 069795a947 FrontRunner/Toucan-AF: drop unnecessary compile time CPU model selection
The first reason for selecting the CPU model at compile time was a
multi-second pause if booting a single core Fusion T40R with MAX_CPUS=2.
Recent tests show the pause has disappeared, someone must have fixed it.

The second reason was me not knowing how to make a single vgabios image
work with two different PCI IDs.  Many thanks to Martin Roth for educating
me!  Quote:

"The way to make coreboot use the same vbios for different video device IDs
 is through the map_oprom_vendev function. In family 14 it's in
 northbridge/amd/agesa/family14/amdfam14_conf.c You would name your video
 bios 1002,9802 in the config and all the other device/vendor IDs for the
 family 14h processors will fall through the initial check for the video
 bios and will get remapped to use that vbios. This only works if you're
 initializing the vbios inside coreboot. I don't know if you're using
 SeaBios as a payload, but if you are you can add the vbios to cbfs as
 vgaroms/vbios.rom and the rom will always be initialized."

I'd like to add the vgabios is added as type 'optionrom' when Coreboot make
adds it, however to work with SeaBios it has to be added manually with
cbfstool and with type 'raw', or it will hang.

Ronald G. Minnich 026bbda071 ARM: remove code that is IMHO a dangerous design
OK, this is tl;dr. But I need to write this in hopes we make
sure we don't put code like this into coreboot. Ever.

Our excuse in this case is that it was imported, not obviously wrong,
and easily changed. It made sense to get it in, make it work, then
do a cleanup pass, because changing everything up front is almost
impossible to debug.

The exynos code has bunch of base register values, e.g.

These are base addresses of things that look like a memory-mapped
struct. To get these to a pointer, they created the following macro,
which creates an inline function.

static inline unsigned int samsung_get_base_##device(void)	\
{								\
	return cpu_is_exynos5() ? EXYNOS5_##base : 0;		\
}

And then invoke it 31 times in a .h file, e.g.:
SAMSUNG_BASE(clock, CLOCK_BASE)

to create 31 functions.

And then use it:
        struct exynos5_clock *clk =
	                (struct exynos5_clock *)samsung_get_base_clock();

OK, what's wrong with this? It's easier to ask what's right with it. Answer: nothing.

I have a long list of what's wrong, and I may leave some things out,
but here goes:
1. the "function" can return a NULL if we're not on exynos5. Most uses of the code
   don't check the return value.
2. And why would this function be running, if we're not on an exynos5? Why compile it in?
3. Note the cast everywhere a samsung_get_base_xxx is used.
   The function returns an untyped variable, requiring the *user* to get two
   things right: the cast, and the function invocation. One can replace that _clock(); with
   _power(); in the code above, and they will be referencing the wrong registers, and
   they'll never get an error!
   We have a C compiler; use it to type data.
4. You're generating 31 functions using cpp each and every time the file is included.
   The C compiler has to parse these each time. It's not at all like a simple cpp
   macro which is only generated on use.
5. You can't tags or etags this code
6. In fact, any kind of analysis tool will be unable to do anything with this cpp magic.

That's only a partial list.

So what's the right way to do it? Just make typed constants, viz:

Or, since I expect people will want the lower case function syntax, I've left
it that way:

Now we've got something that is efficient, and we don't even need to protect with
any more.

Hence this change. We've got something that is type checked, does not require users to
cast on each use, will catch simple programming errors, can be analyzed with standard tools,
and builds faster.

So if we make a mistake:
       struct exynos5_clock *clk =
                       samsung_get_base_adc();

We'll see it:
src/cpu/samsung/exynos5250/clock.c: In function 'get_pll_clk':
src/cpu/samsung/exynos5250/clock.c:183:3: error: initialization from incompatible pointer type [-Werror]

which we would not have seen before.

As a minor benefit, it shaves most of a second off the compilation.

Jens Rottmann f91c8f290b FrontRunner/Toucan-AF: work around AGESA RAM init crashing on reboot
If you try to reset the system with outb(3,0x92), outb(4,0xcf9) or a
triple-fault it will instead crash with a messy screen.  As the more common
outb(0xFE, 0x64) doesn't work with our setup, Linux will crash whenever you
ask it to reboot.  Closer inspection shows that on a warm boot of Coreboot
agesawrapper_amdinitpost() always fails with error code 7.  Looks like DDR3
re-init goes wrong somehow.  I tried find the reason for this but was
unable to.  I am convinced this is not board specific but a bug in AGESA.

In the end I had to settle for a workaround:  if amdinitpost returns 7 this
patch resets the system harder with outb(0x06, 0x0cf9), after that RAM init
will succeed.  As amdinitpost is early in POST this automatic reset is
quick enough not to be noticable.

I'd perfer a real fix, but that's all I have.

Jens Rottmann 68c9f2bdc5 LiPPERT Toucan-AF [2/2]: actually implement mainboard support
Step 2: change the Persimmon code to adapt it to the new board's hardware.

The Toucan-AF is a COM Express Compact Type 6 form factor embedded board:
- AMD Fusion G-T56N (1.65 GHz dual core) or T40R (1 GHz single core) APU
  - 1-4 GB DDR3 memory down
  - 1x VGA, 2x DisplayPort (1 switchable to LVDS)
- AMD A55E (Hudson-E1) southbridge
  - 8x USB 2.0
  - 4x SATA
  - HD Audio (with codec on baseboard)
  - NEC uPD78F0532 microcontroller on I2C ("SEMA")
- 7x PCIe2.0 x1 (1 on PEG)
- Intel I210 GbE (on APU PCIe x1, can be disabled for additional PCIe)
- 2x SST 25VF032B (SO8, soldered) 4 MB SPI flash (BIOS and failsafe BIOS)

The Toucan-AF has no SIO on board.  This patch includes basic support for a
Winbond W83627DHG (PS/2, 2x RS232), because the ADLINK ExpressBase-6 used
for evaluation happens to have one.  The code may have to be adapted to the
actual baseboard of the application.

This breaks booting, and in fact stages.c is always going to be special: for it to work it has to be compiled for arm only, no thumb allowed. It's probably better to leave the stages.o target in explicitly so it's clear that it has to be compiled with a particular set of flags, rather than try to remember that we must always have the default rules no break stages.c compilation. That would be a mess. I will be pushing a CL to get rid of the assembly dump, but will be a trivial fix.

Paul Menzel 4fc600442b AMD Fam14 boards: Set P_BLK length to 6 for all processors
Currently on for example on AMD Persimmon and ASRock E350M1 Linux
complains, that the PBLK length is invalid [1].

        ACPI: Invalid PBLK length [0]

Consequently, frequency scaling might not work correctly, though for
these two boards it seems to work according to PowerTOP.

Indeed, according to the ACPI specification [2], setting PBlockLength
to 0 is only allowed if there is no PBlockAddress. Otherwise it has to
be set to 6.

        18.5.93 Processor (Declare Processor)

        […]

        PBlockAddress provides the system I/O address for the processors
        register block. Each processor can supply a different such
        address. PBlockLength is the length of the processor register
        block, in bytes and is either 0 (for no P_BLK) or 6. With one
        exception, all processors are required to have the same
        PBlockLength. The exception is that the boot processor can have
        a non-zero PBlockLength when all other processors have a zero
        PBlockLength. It is valid for every processor to have a
        PBlockLength of 0.

And that is exactly what Linux is checking in
`drivers/acpi/processor_driver.c` [3].

        static int acpi_processor_get_info(struct acpi_device *device)
        {

                }
        […]
        }

This issue has proliferated to all AMD based boards so fix it for
all of them by setting P_BLK length to 6.

The DSDT of for example AMD Parmer and AMD Thatcher also set it
to 6 everywhere so this solution is taken instead of setting the
P_BLK system I/O base to 0 for all but the first processor which
is how it is done for earlier AMD based boards.

As note having to set this manually should not be needed and
this should be autogenerated as done for most of the Intel boards
and the AMD K8 based boards (`src/cpu/amd/model_fxx/powernow_acpi.c`).

Paul Menzel 12d60247ab AMD boards: ACPI DSDT: Use COREBOOT for the OEM Table ID field
The DSDT header contains the fields OEMID and OEM Table ID. See
for example ACPI specification 4.0a [1]

    5.2.11.1 Differentiated System Description Table (DSDT)

on page 135. There Table 5-16 contains the descriptions.

Field         Byte Length  Byte Offset  Description
===================================================
OEMID         6            10           OEM ID
OEM Table ID  8            16           The manufacture model ID.

Currently in coreboot there is no common method what to put in
these fields.

Mostly Intel based boards populate it with "CORE  " ore "COREv4"
and AMD based boards populate it with the board vendor and
model number, abbreviated appropriately to fit into these fields.

On most boards the proprietary vendor BIOS seems to leave these
fields – displayed with `sudo dmidecode` under System Information –
blank

    To Be Filled By O.E.M.

and fill out the Base Board Information with the board vendor and
model name.

In [2] Jens Rottmann argues that the this is really just the table
ID used for naming it and that »99% of the DSDT code is not board
specific«.

Both approaches seem to have their advantages, but using the
second one, developers often seem to forget to update them (for
example AMD Thather).

The current situation is at least not optimal. and therefore at
least unify the string in the OEM Table ID. If unifying the
OEM ID is also a good idea this should be done too.

If later on it should be decided that the board vendor and model
should be used again, this should be somehow derived from
Kconfig.

The following command was used for the change [3].

    $ git grep -l '\/\* TABLE ID \*\/' | xargs sed -i '/TABLE ID/s/"\([^"]*\)"/"COREBOOT"/'

This patch is split out from [2].

Enable CHROMEOS configure option on snow. Write gpio support code for

"virtual" GPIOs.

Add a chromeos.c file for snow, needed to build.

This is tested and creates gpio table entries that our hardware can use.

Lots still missing but we can now start to fill in the blanks, since
we have enabled CHROMEOS for this board. We are getting further into
the process of actually booting a real kernel.

To reduce the differences between these file name the enabling

Thanks to the awesome help of gnomon and BlastHardcheese in the

following command to do the actual work.

    $ cd src/mainboard
    $ for f in */*/mainboard.c ; \
    > do src="$(awk '/\.enable_dev = /{v=$NF; sub(/,$/,"",v); print v}' "$f")" ; \
    > [[ -z $src ]] && continue ; \
    > printf '%s\n' "g/${src}/s/${src}\([,(]\)/mainboard_enable\1/p" w | ed -s "$f" ; \
    > done

`src/mainboard/digitallogic/msm586seg/mainboard.c` and
`src/mainboard/technologic/ts5300/mainboard.c` had to be adapted
manually as no comma was used separating the struct members.

And with the following statement, gnomon is even more likable!

    My pleasure entirely.  Good luck with coreboot; I'm a big fan of the project.

Jens Rottmann 940095fe5e AMD based boards: platform_cfg.h: Replace `_*BOARDNAME*_CFG_H_` with `_PLATFORM_CFG_H_`
Reduce unnecessary differences between AMD based boards only
using the file `platform_cfg.h` for configuration making them
a little bit easier to compare.

Inagua & co. mention the board name in several places which are really not
that board specific.  Sometimes people even forget to change it:
Union Station’s platform_cfg.h starts with "#ifndef _PERSIMMON_CFG_H_".
Funny.  Change that to "_PLATFORM_CFG_H_" everywhere.

The following command was used.

    $ find . -name platform_cfg.h | xargs sed -i '/_CFG_H_/s/_.*_/_PLATFORM_CFG_H_/'

More boards seem to use that kind of naming (`git grep _CFG_H_`)
but it is not certain that this will not break anything as for
example the board AMD Dinar also has header files for
configuration stuff for the north- and southbridge.

    $ git grep _CFG_H_

    printk(BIOS_DEBUG, "alib\n");
    dump_mem(ssdt, ((void *)alib) + alib->length);

which is enclosed `#if DUMP_ACPI_TABLES == 1` to dump the ACPI
tables.

Basically the whitespace in the license header in Inagua’s file
was fixed and then the file copied over to the other directories.

Ronald G. Minnich 601b27596f ARMV7: minor tweaks to inter-stage calling and payload handling.
Payloads, by design, can return. There's lots of mechanism in the payload code
to support it, and the chooser payload relies on it. Hence, we should not mark
the function call in exit_stage as noreturn.

Not all ARM have unified caches, and it's not always easy to tell what
to do. So we are very paranoid. Before we call between stages, we
should carefully flush the dcache to memory and invalidate the icache.
This may be more than is necessary on all architectures but it
doesn't really hurt for the most part.

So compile cache management code into all stages, and call the
flush dcache/invalidate icache from all stages.

    #ifndef AZALIA_SDIN_PIN
    #define AZALIA_SDIN_PIN              0x2A

    […]
    	sb_config->AzaliaSdin0 = AZALIA_SDIN_PIN;
    […]

The 8 bit value 0x2A (binary 00 10 10 10), was being used incorrectly
– I believe the original intent of this value was to enable the SDIN
pins 0, 1, & 2. Because it was getting truncated as it was put into
AzaliaSdin0, this wasn't happening and only SDIN0 was being enabled.

I am leaving only SDIN0 enabled at this point to as not change the
actual behavior on the platform.

Jens Rottmann 384ee9f142 Persimmon: drop useless DDR3 voltage code copied from Inagua
Inagua can use GPIOs 178,179 to switch VMEM to 1.5, 1.35 or 1.25 V,
which it does according to data read from the SO-DIMM's SPD EEPROM.

On Persimmon (according to DB-FT1 rev. D schematics) both GPIOs are
unconnected, there is no way to change the 1.5 V DDR3 voltage (save
unsoldering a resistor). The whole code copied over from Inagua is
useless.

Removed the code, instead a comment hints at Inagua, for people who do designs
based on Persimmon but do have a way to change VMEM.

The line ...->DDR3Voltage = VOLT1_5; is supposed to make the AGESA DDR3 code
select the RAM timings for the actually supplied voltage instead of the
hoped-for but unavailable lower voltage. I have no idea how to test this, but
in any case it can't hurt.

Jens Rottmann fa8702cf2a Persimmon: adapt PCIe reset code copied from Inagua to actually match Persimmon
Comparing Persimmon and Inagua schematics and Coreboot code show the PCIe reset
code has been blindly copied even though it doesn't suit the Persimmon at all.

The Inagua can employ GPIOs 21, 25, 02 to manually reset devices on APU PCIe
lanes 0/1, 2, 3 respectively. (Appearently the motivation for this is to revive
buggy PCIe gen1 devices which got confused by PCIe gen2 signal training.)

However the Persimmon not only doesn't support this, it even needs these 3 pins
for the PCI interface! Instead it uses GPIO50 to reset devices on lanes 0-2 all
at once. Lane 3 is unconnected anyway.

This patch adapts the Persimmon mainboard code according to the DB-FT1 rev. D

Zheng Bao ca6e1f6c04 AMD S3: Program the flash in a bigger data packet
According to spi.c in src/southbridge/amd/agesa/hudson
readwrite = (bytesin + readoffby1) << 4 | bytesout;
We can see that Hudson limits the SPI programming data
packet size as 15.

We used to write data to SPI in dword mode. It didn't
take full advantage of the data packet size. We need to
leverage that to speed up programming time.

Martin Roth 92f03c0a06 AMD Family12h: Fix warnings
Add needed prototypes to .h files.
Remove unused variables and fix types in printk statements.
Add #IFNDEFs around #DEFINEs to keep them from being defined twice.
Fix a whole bunch of casts.
Fix undefined pre-increment behaviour in a couple of macros.  These now
  match the macros in the F14 tree.
Change a value of 0xFF that was getting truncated when being assigned
  to a 4-bit bitfield to a value of 0x0f.

This was tested with the torpedo build.
This fixes roughly 132 of the 561 warnings in the coreboot build
  so I'm not going to list them all.
  Here is a sample of the warnings fixed:

David Hendricks 882fdcf227 armv7/exynos5250: fix usage of _stack and _estack
This patch fixes up the usage of stack pointer and regions.
The current approach only works by coincidence, so this fixes a few
things at once to get it into a working state and allow us to use
checkstack() again:

- Add a STACK_SIZE Kconfig variable. Earlier on it was evaluated to 0.

- Assign _stack and _estack using CPU-specific Kconfig variables since
  it may reside elsewhere in memory (not necessarily DRAM).

- Make the existing IRAM stack variables more useful in this context.

global data. Since we're trying to avoid that, we added start and size
parameters so that board-specific info can be passed in via mainboard
code. Let's start using it that way.

Konstantin Aladyshev 3d990ffc88 Supermicro H8QGI: Substract 1 from MMCONF range limit
MMCONF space is defined by two config parameters:
MMCONF_BASE_ADDRESS (0xF800 0000)
MMCONF_BUS_NUMBER (64)

Coreboot allocates 1MB per bus, so MMCONF limit should be:
0xF800 0000 + 64*(0x0010 0000) - 1 = 0xFBFF FFFF

Current code does not have (-1) component, this makes MMCONF limit
equal 0xFC00 FFFF. Not 0xFC00 0000, because according to BKDG
lower two bytes of MMIO limit always equal 0xFFFF:
MMIOLimit = {MMIOLimitRegister[47:16], FFFFh}.

Add (-1) to correct this issue.

No functionality change has been experienced. The five times
slower RAM speed compared to the proprietary vendor BIOS still
remains.

Add a prototype to a .h file
Remove an unused file (GppHp.c) from the build by deleting it from the

RAMBASE and RAMTOP are leftovers from the x86 port and do not apply
the same way on ARM platforms. On x86 they refer to the low memory
region where coreboot tables reside.

However on ARM we don't have such a region which is architecturally
defined. So instead we'll use the CPU-defined DRAM base address and
the mainboard-defined DRAM size.

This also has the pleasant side-effect of fixing the coreboot tables
to not clobber ramstage code...

This hit me when running the latest Qemu with coreboot:

The iPXE OPROM has no int10 support (obviously) so calling
vbe_set_graphics() wipes the framebuffer information from

The common part of the bootblock resets the nvram data if it's found
to be invalid. Since that code is compiled with romcc in i386 mode,
there's a shortage on registers.

Try to reduce the strain by doing things smarter: cmos_write_inner
is the same as cmos_write, just that it doesn't check if the RTC is
disabled. Since we just disabled it before, we can assume that it is so.

David Hendricks 0d4f97e270 exynos/snow: Move core/memory clock-related and board ID code
This patch moves ARM core and DRAM timing functions around to simplify
the dependencies for system_clock_init().

The original code was architected such that the system_clock_init()
function called other functions to obtain core and memory timings.
Due to the way memory timing information must be obtained on Snow,
which entails decoding platform-specific board straps, the bottom-
up approach resulted in having the low-level clock init code
implicitly depend on board and vendor-specific info:

main()
  ->system_clock_init()
    -> get_arm_ratios()
       -> CPU-specific code
    -> clock_get_mem_timings()
       -> board_get_revision()
          -> read GPIOs (3-state logic)
          -> Decode GPIOs in a vendor-specific manner
       -> Choose memory timings from module-specific look-up table
  ...then proceed to init clocks
...come back to main()

The new approach gathers all board and vendor-specific info in a
more appropriate location and passes it into system_clock_init():
main()
  -> get_arm_ratios()
     -> CPU-specific code
  -> get_mem_timings()
     -> board_get_config()
        -> read GPIOs (3-state logic)
        -> Decode GPIOs in a vendor-specific manner
     -> Choose memory timings from module-specific look-up table
  -> system_clock_init()
...back to main()

    "-H": header offset. When omitted, put header right before bootblock,
          and update a top-aligned virtual address reference in end of ROM.

  Example: (can be found in ARM MAkefile):
    cbfstool coreboot.rom create -m armv7 -s 4096K -B bootblock.bin \
             -a 64 -b 0x0000 -H 0x2040 -o 0x5000

David Hendricks 2354ef8869 exynos/snow: get rid of board-specific arbitration code
Snow's AP, EC, PMU, and smarty battery share a bus. Both the AP and
EC can act as a master, so to avoid conflicts an arbitration
mechanism consisting of two GPIOs is used.

By default, the AP "owns" the bus unless it is off (in which case
the EC doesn't monitor the arbitration pins). This means the boot
firmware does not need to worry about these lines. The payload may
if it needs to communicate with the EC, though.

In any case, board-specific bus arbitration logic does not belong
in a low-level driver that is supposed to be generic for an entire
CPU family. If the payload needs to talk to the EC, we'll deal with
it there.

For ARM platform, the bootblock may need more C source files to initialize
UART / SPI for loading romstage. To preventing making complex and implicit
dependency by using #include inside bootblock.c, we should add a new build class
"bootblock".

Also #ifdef __BOOT_BLOCK__ can be used to detect if the source is being compiled
for boot block.

For x86, the bootblock is limited to fewer assembly files so it's not using this
class. (Some files shared by x86 and arm in top level or lib are also changed
but nothing should be changed in x86 build process.)

'src' is aligned but LZMA_PROPERTIES_SIZE may refer to an unaligned address like

this will fail on systems using big-endian (outSize was encoded in

Ronald G. Minnich 79e36d9060 Improve how our printk calls do_div by using constants.
The do_div code has a nice optimization in it when it is called with
constants. The current highly generalized use of it defeats those
optimizations and causes trouble on ARM, resulting in a complex and
buggy code path.

Since we only need to print in bases 8, 10, and 16, do a minor
restructuring of the code so that we call do_div with constants.
If you need base 2, print in base 16 and do it in your head. :-)

This fixes an ongoing problem with ARM, will not harm X86, and will
help PPC should we ever want to support it again.
Plus, I don't have to ever try to understand the div64 assembly and where
it's going wrong :-)

Hung-Te Lin 6fe0cab205 Extend CBFS to support arbitrary ROM source media.
Summary:
	Isolate CBFS underlying I/O to board/arch-specific implementations as
	"media stream", to allow loading and booting romstage on non-x86.

	CBFS functions now all take a new "media source" parameter; use
	CBFS_DEFAULT_MEDIA if you simply want to load from main firmware.
	API Changes:
		cbfs_find => cbfs_get_file.
		cbfs_find_file => cbfs_get_file_content.
		cbfs_get_file => cbfs_get_file_content with correct type.

CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM,
the ROM may come from USB, UART, or SPI -- any serial devices and not available
for memory mapping.

To support these devices (and allowing CBFS to read from multiple source
at the same time), CBFS operations are now virtual-ized into "cbfs_media".  To
simplify porting existing code, every media source must support both "reading
into pre-allocated memory (read)" and "read and return an allocated buffer
(map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*"
provides simple memory mapping simulation.

Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA
is defined for CBFS functions to automatically initialize a per-board default
media (CBFS will internally calls init_default_cbfs_media).  Also revised CBFS
function names relying on memory mapped backend (ex, "cbfs_find" => actually
loads files). Now we only have two getters:
	struct cbfs_file *entry = cbfs_get_file(media, name);
	void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type);

Test results:
 - Verified to work on x86/qemu.
 - Compiles on ARM, and follow up commit will provide working SPI driver.

It can be handy to have debug prints as DRAM is started up, so that
in the case of failure (does that ever happen?) you've got some
idea where it failed.

This patch adds some DEBUG_SPEW prints to the DDR3 code. I am doing this

but it is not impossible if we skew the timing in some way.

Ronald G. Minnich 770996fd86 Exynos5250: make vendor enums in the timing array more debuggable.
The timing array is crucial to proper operation of DRAM.

Getting a valid pointer to it is hence very important. Unfortunately,
the constants chosen for the vendor were '1', and '2', (this in a
32-bit word) which in a debug print makes it almost impossible to tell
if you've got a misaligned pointer. Note: coreboot people did not
choose them :-)

So, give them values which are extremely unlikely to occur elsewhere
in the array (or in memory, for that matter).

Given the frequency with which this check occurs, i.e. once, I would
much prefer strings but I expect I'd get shouted down on that
one. Constants in this case are an almost useless optimization but
we'll go with them for now. Note no space is saved by not using
strings: there's an entire function somewhere devoted to mapping the
enum to a string!

Debug prints of pointers to structs in this array are now far more
useful than they were.

See snarky comment in the code (left there to make sure nobody gets
tempted to get fancy again). Comment now less snarky.

This is tested on google snow to the point that the DRAM works.

The way that devicetree.cb was configured for the family 15tn boards

This was causing S3 resume to fail.

There is a disconnect between how the devicetree should be configured
if there are multiple HT links on the CPU and how it's configured if
there's only one HT link.  These platforms were set up as if they
had multiple HT links, which was causing duplicate instances of
devices in the device list.

The scan for the IO Hub was removed from the northbridge code which
isn't a problem for F15tn devices.

David Hendricks 211a5d56db armv7/snow: get to romstage
This patch does a few things to get us into romstage:
- Add romstage as a stage (a later patch adds it as a binary, which
  is probably wrong). The Makefile magic is complex enough that we
  let it build the XIP file for now, but we no longer use it.

- Replace findstage with loadstage. Loadstage will find a stage,
  load the code to memory, and zero the remaining part of memory.
  Now we can link the romstage to go anywhere!

- Eliminate magic offsets from code/ldscripts and centralize Kconfig
  variables in src/cpu/samsung/exynos5250/Kconfig.

- Tidy up code and serial output

Gabe Black 929f9f1719 armv7: add a wrapper for romstage's main() for ARM ISA
This adds a wrapper around main() in romstage which is compiled using
-marm. This assumes that the bootblock branches to romstage in ARM
mode.

The long-term idea is to enforce ABI compatibility when handing off to
the next stage by using shims which are which are compiled in a pre-
determiend manner and leave the main portions of each stage up to
whatever the compiler wants. So it will eventually look like this:
1. bootblock_main (ARM/Thumb)
2. bootblock_exit (ARM)
3. romstage_entry (ARM)
4. romstage_main (ARM/Thumb)

(credit to Gabe Black for writing the patch, I'm just uploading it)

to using a real bootblock for ARM, so add romstage.c to the files
compiled and we'll make main() our entry point.

This also updates romstage.ld to place main() (*(.text.startup)) at
the beginning of romstage.

David Hendricks 0b23d47ffd armv7: Place reset vector + CBFS header + bootblock dynamically
This replaces hard-coded bootblock offsets using the new scheme.
The assembler will place the initial branch instruction after BL1,
skip 2 aligned chunks, and place the remaining bootblock code after.

It will also leave an anchor string, currently 0xdeadbeef which
cbfstool will find. Once found, cbfstool will place the master CBFS
header at the next aligned offset.

Here is how it looks:

             0x0000 |--------------|
                    |     BL1      |
             0x2000 |--------------|
                    |    branch    |
    0x2000 + align  |--------------|
                    |  CBFS header |
0x2000 + align * 2  |--------------|
                    |   bootblock  |
                    |--------------|

TODO: The option for alignment passed into cbfstool has always been
64. Can we set it to 16 instead?

This lays out the groundwork for using a proper bootblock on ARM.
Currently we bypass the bootblock entirely and go straight to
romstage. However we want to utilize CBFS to maximize flexibility
of placing code without relying on a lot of magic numbers which
will break depending on the SoC in use.

Stefan Reinauer d37ab454d4 Implement GCC code coverage analysis
In order to provide some insight on what code is executed during
coreboot's run time and how well our test scenarios work, this
adds code coverage support to coreboot's ram stage. This should
be easily adaptable for payloads, and maybe even romstage.

See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for
more information.

To instrument coreboot, select CONFIG_COVERAGE ("Code coverage
support") in Kconfig, and recompile coreboot. coreboot will then
store its code coverage information into CBMEM, if possible.
Then, run "cbmem -CV" as root on the target system running the
instrumented coreboot binary. This will create a whole bunch of
.gcda files that contain coverage information. Tar them up, copy
them to your build system machine, and untar them. Then you can
use your favorite coverage utility (gcov, lcov, ...) to visualize
code coverage.

For a sneak peak of what will expect you, please take a look
at http://www.coreboot.org/~stepan/coreboot-coverage/

Siyuan Wang 3d4762d450 Tyan s8226: change lapic of lapic_cluster 0 to 0x10
There are two CPUs on s8226 and each CPU has 8 cores.
CPU 0 takes lapic from 0x10 to 0x17 and CPU 1 takes from 0x20 to 0x27.
So the first core's lapic is 0x10 rather than 0x20.

David Hendricks 6a503b6a0f make early serial console support more generic
This patch makes pre-RAM serial init more generic, particularly for
platforms which do not necessarily need cache-as-RAM in order to use
the serial console and do not have a standard 8250 serial port.

This adds a Kconfig variable to set romstage-* for very early serial
console init. The current method assumes that cache-as-RAM should
enable this, so to maintain compatibility selecting CACHE_AS_RAM will
also select EARLY_SERIAL_CONSOLE.

The UART code structure needs some rework, but the use of ROMCC,
romstage, and then ramstage makes things complex.

uart.h now includes all .h files for all uarts. All 2 of them.
This is actually a simplifying change.

David Hendricks 10c90d3126 update CFLAGS for armv7
This updates $CFLAGS used for armv7. Most of them were just added
to be consistent with what u-boot does. The important ones here
are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions).

I removed the hard float support because it got errors and
coreboot should never use floats anyway. We're still having trouble
with enums but I want to see how far it gets with this patch.

Also, put the flags in a form that makes diffs easier to read. It's
almost impossible otherwise.

Finally, move some flags to the architecture Makefile, and
rely on the fact that some are set for all architectures.

Aladyshev Konstantin f50fbe82ad AGESA: Use `Flag=AGESA_SUCCESS` instead of `TRUE` in DMI related functions
Success return value in DMI functions GetDmiInfoMain(..) and GetType4Type7Info(...) of AGESA vendorcode is "Flag = TRUE".

This results in a failure of init late function:

    "agesawrapper_amdinitlate failed: 1"

It happens because TRUE = 1 = AGESA_UNSUPPORTED.

Replacing TRUE with AGESA_SUCCESS (= 0) fixes this problem.

Only family f15tn does not have such bug.

This patch just replaces TRUE with AGESA_SUCCESS, but maybe all DMI functions should be copied from Trinity family?

Martin Roth e899e518d8 SB800: Add IMC ROM and fan control.
Add configuration for AMD's IMC ROM and fan registers for cimx/sb800
platforms.

- Allows user to add the IMC rom to the build and to configure the
  location of the "signature" between the allowed positions.
- Allows for no fan control, manual setup of SB800 Fan registers, or
  setup of the IMC fan configuration registers.
- Register configuration is done through devicetree.cb. No files need
  to be added for new platform configuration.
- Initial setup is for Persimmon, but may be extended to any cimx/sb800
  platform.

Martin Roth a17fd056d4 Rename generated hudson_romsig.bin for make clean
The file generated when the IMC or XHCI binaries are included in the rom
was named $(obj)/hudson_romsig.bin.  The problem with this is that it
doesn't get deleted when the user does a make clean.
changing the name to coreboot_hudson_romsig.bin makes this happen.

Martin Roth 3aef7b4f63 Fix SPI BAR special case in lpc_set_resources
There was already a special case for the SPI base address in
lpc_set_resources for southbridge/amd/cimx/sb800 and
southbridge/amd/agesa/hudson, but it needed to be modified
to keep from killing the IMC rom during initialization.  As
soon as the BAR is disabled by setting the new base address,
the IMC dies.  The fix is to make sure it's still enabled
when setting the new base address instead of setting the new
address then re-enabling it.

Change the name SPIROM_BASE_ADDRESS to SPIROM_BASE_ADDRESS_REGISTER
to more accurately describe what we're using.

Martin Roth 3316cf2ff8 Claim the SPI bus before writes if the IMC ROM is present
The SB800 and Hudson now support adding the IMC ROM which runs from the same
chip as coreboot.  When the IMC is running, write or erase commands sent to
the spi bus will fail, and the IMC will die.  To fix this, we send a request
to the IMC to stop fetching from the SPI rom while we write to it. This
process (in one form or another) is required for writes to the SPI bus while
the IMC is running.

Because the IMC can take up to 500ms to respond every time we claim the
bus, this patch tries to keep the number of times we need to do that to a
minimum.  We only need to claim the bus on writes, and using a counter for
the semaphore allows us to call in once to claim the bus at the beginning
of a number of transactions and it will stay claimed until we release it
at the end of the transactions.

Claim() - takes up to 500ms hit
    claim() - no delay
        erase()
    release()
    claim() - no delay
        write()
    release()
Release()

Supermicro h8scm has a C32 CPU socket, the details of this board is:
http://www.supermicro.com/Aplus/motherboard/Opteron4100/SR56x0/H8SCM-F.cfm
We are planning to replace legacy C32 code with agesa and the h8scm_fam10 do not support
family 15 CPU, so we update this mainboard with this patch.

This code supports memory at 800M Hz of f10 CPU, bu f15 CPU does not has this limitation.
If you want to change the frequency of memory, please edit the macros
"BLDCFG_MEMORY_BUS_FREQUENCY_LIMIT" and "BLDCFG_MEMORY_CLOCK_SELECT"
in src/mainboard/supermicro/h8scm/buildOpts.c

Patrick Georgi bbc880eee7 amdk8/amdfam10: Use CAR_GLOBAL for sysinfo
This gets rid of the somewhat unstructured placement of AMD's
sysinfo structure in CAR.
We used to carve out some CAR space using a Kconfig variable,
and then put sysinfo there manually (by "virtue" of pointer magic).

Now it's a variable with the CAR_GLOBAL qualifier, and build
system magic.

For this, the following steps were done (but must happen together
since the intermediates won't build):
- Add new CAR_GLOBAL sysinfo_car
- point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR
- remove DCACHE_RAM_GLOBAL_VAR_SIZE
  - from CAR setup (no need to reserve the space)
  - commented out code (that was commented out for years)
  - only copy sizeof(sysinfo) into RAM after ram init, where
    before it copied the whole GLOBAL_VAR area.
  - from Kconfig

David Hendricks 6b908d08ab Make POST codes written to IO port optional
This adds more configurability to POST codes. The current assumption
is that POST codes should be written to an IO port (e.g. LPC) if POST
codes are enabled. This changes the assumption so that POST codes can
be written to the serial console without being written to an IO port.

This enables POST codes by default using "default y" to avoid
changing current behavior.

- the x86 realmode interrupt handlers changed in signature
- to access registers, use X86_$REGNAME now (eg. X86_EAX)

Duncan Laurie 11290c49b0 SMM: Restore GNVS pointer in the resume path
The SMM GNVS pointer is normally updated only when the
ACPI tables are created, which does not happen in the
resume path.

In order to restore this pointer it needs to be available
at resume time.  The method used to locate it at creation
time cannot be used again as that magic signature is
overwritten with the address itself.  So a new CBMEM ID
is added to store the 32bit address so it can be found
again easily.

A new function is defined to save this pointer in CBMEM
which needs to be called when the ACPI tables are created
in each mainboard when write_acpi_tables() is called.

The cpu_index variable had to be renamed due to a conflict
when cpu/cpu.h is added for the smm_setup_structures()
prototype.

Bill Richardson 0a405bafc5 cros: Inform U-Boot via fake gpio when VGA Option ROM is loaded
This prepares the way for vboot to inform coreboot when it needs the VGA
Option ROM loaded. Coreboot can't always know when it's needed (with
keyboard-based dev-mode, coreboot can't tell if we're in dev-mode or not).
By the time we get to U-Boot, it's too late, so we need two extra bits - one
for vboot to tell coreboot to load the Option ROM and another for coreboot
to let vboot know it's been done.

This change sets up the communication, but doesn't act on it just yet.

Even with this CL we always load the VGA Option ROM, so there's nothing to
test. There should be no user-visible change.

Ronald G. Minnich 000bf83c93 Support better tracking of AP stack usage.
This change allows us to figure out how much of the AP stacks we are
using, as well as to catch any case of an AP overrunning its stack.
Also, the stack is poisoned, which is a good way to catch programming
errors -- code should never count on auto variables being zerod.

The stack bases are recorded in a new array, stacks. At the end,
when all APs are initialized, the stacks are walked and the
lowest level of the stack that is reached is printed.

Build and boot and look for output like this:

CPU1: stack allocated from 00148000 to 00148ff4:\
	lowest stack address was 00148c4c
CPU2: stack allocated from 00147000 to 00147ff4:\
	lowest stack address was 00147c4c
CPU3: stack allocated from 00146000 to 00146ff4:\
	lowest stack address was 00146c4c

Note that we used only about 1K of stack, even though in this
case we allocated 4K (and in the main branch, we allocate 32K!)

Duncan Laurie d4bc067954 SPI: Add early romstage SPI driver using hardware sequencing
This is a basic romstage driver that can be used for the
MRC cache code on systems where we do not have the MRC cache
stored in a flash region that is memory mapped.

It uses the hardware sequencing interface to avoid having
to know anything about the flash chip itself.

BUG=chrome-os-partner:15031
BRANCH=stout

that attempted to read the MRC cache at offset 0x3e0000.

Duncan Laurie 215f278563 ELOG: Support for non-memory mapped flash
If the event log is stored in flash that is not memory
mapped then it must use the SPI controller to read from
the flash device instead of relying on memory accesses.

In addition a new CBMEM ID is added to keep an resident
copy of the ELOG around if needed.  The use of CBMEM for
this is guarded by a new CONFIG_ELOG_CBMEM config option.
This CBMEM buffer is created and filled late in the process
when the SMBIOS table is being created because CBMEM is
not functional when ELOG is first initialized.

The downside to using CBMEM is that events added via the
SMI handler at runtime are not reflected in the CBMEM copy
because I don't want to let the SMM handler write to memory
outside the TSEG region.

In reality the only time we add runtime events is at kernel
shutdown so the impact is limited.

Test:
1) Test with CONFIG_ELOG_CBMEM enabled to ensure the event
log is operational and SMBIOS points to address in CBMEM.
The test should involve at least on reboot to ensure that the
kernel is able to write events as well.

Duncan Laurie 23b0053586 SPI: Fix and enable Fast Read support
- Fix handling of 5-byte Fast Read command in the ICH SPI
driver.  This fix is ported from the U-boot driver.
- Allow CONFIG_SPI_FLASH_NO_FAST_READ to be overridden by
defining a name for the bool in Kconfig and removing the
forced select in southbridge config
- Fix use of CONFIG_SPI_FLASH_NO_FAST_READ in SPI drivers
to use #if instead of #ifdef
- Relocate flash functions in SMM so they are usable.
This really only needs to happen for read function pointer
since it uses a global function rather than a static one from
the chip, but it is good to ensure the rest are set up
correctly as well.

Duncan Laurie 2a700ec163 SPI: Configure Software Sequence SPI Freq to match descriptor
Right now the SPI bus is getting set to 20mhz for transactions
initiated with the software sequence interface.

In order to be able to do reasonable fastread/write/erase we
can bump this up to a higher value at boot before it gets
locked at 20mhz.

To do this read out the speed set in the SPI descriptor for
hardware sequencing and apply it to software sequencing.
