Aaron Durbin a267161362 haswell: unify romstage logic
This commit pulls in all the common logic for romstage into
the Haswell cpu directory. The bits specific to the mainboard
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 3bf0ce79b9 rmodule: add 16 bytes of padding
There is a plan to utlize rmodules for loading ramstage as a
relocatable module. However, the rmodule header may change.
In order to provide some wiggle room for changing the contents
of the rmodule header add some padding. This won't stop the need
for coordinating properly between the romstage loader that may be
in readonly flash and rmodule header fields.  But it will provide
for a way to make certain assumptions about alignment of the
rmodule's program when the rmodule is compressed in the flash.

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 21efd8c037 haswell: fix ACPI MCFG table
The acpi_fill_mcfg() was still using ivy/sandy PCI device ids which Hawell
obviously doesn't have. This resulted in an empty MCFG table. Instead of
relying on PCI device ids use dev/fn 0/0 since that is where the host
bridge always resides. Additionally remove the defines for the IB and SB
pci device ids. Replace them with mobile and ult Haswel device ids and
use those in the pci driver tables for the northbridge code.

Booted to Linux and noted that MCFG was properly parsed.

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.

Aaron Durbin 239c2e843f haswell platforms: restructure romstage main
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.

Lastly, drop a comment describing AP startup flow through coreboot.

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.

Mike Loptien 8c72670ba5 AMD Fam14 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.

The Link native graphics commit 49428d84 [1]

    Add support for Google's Chromebook Pixel

was missing some of the higher level bits, and hence could not be
used.  This is not new code -- it has been working since last
August -- so the effort now is to get it into the tree and structure
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
coreboot tree is called Link, and that name is what we will use
in our commits.

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.

This is a 1KB region and so needs to be moved as well so it does
not conflict with other IO regions.

Also expose the gpio_get functions to ramstage and move the
prototypes to pch.h so they can be used for both GPIO interfaces.

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.

tell the OS that it cannot control any PCIe

David Hendricks d2bed05e6a exynos5250/snow: call PMIC's power_init() function
Call the power_init() function. We appear to have forgotten about it
when deprecating lowlevel_init_subsystems(), but it didn't seem to
cause problems until we got to doing more interesting stuff recently.

There are some clean-ups to do from the original code, such as not
attempting to configure I2C from PMIC code, which we'll get around
to in follow-up patches.

(Credit to Gabe for spotting this)

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.

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/

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.

- 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.

Ronald G. Minnich 27bd64a8be Revert "ARMv7: drop special handling for stages.c"
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.

This reverts commit 8f4647a24b

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)
        {
        […]
                /*

                if (!object.processor.pblk_address)
                        ACPI_DEBUG_PRINT((ACPI_DB_INFO, "No PBLK (NULL address)\n"));
                else if (object.processor.pblk_length != 6)

                }
        […]
        }

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].

Ronald G. Minnich 3faa2c77ed google/snow: enable GPIO entries and CHROMEOS in building
These were not separable or it would have been two CLs.

Enable CHROMEOS configure option on snow. Write gpio support code for
the mainboard.  Right now the GPIO just returns hard-wired values 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.

Paul Menzel 528640d141 mainboard.c: Name enable_dev function uniformly `mainboard_enable`
To reduce the differences between these file name the enabling
device function in the directory `src/mainboard` uniformly
`mainboard_enable` [1].

Thanks to the awesome help of gnomon and BlastHardcheese in the
IRC channel #sed on <irc.freenode.net>. gnomon came up with 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_
    […]

Ronald G. Minnich 836fd19aa8 armv7: Don't let users set ram parameters that are fixed in hardware.
The SDRAM base is fixed in hardware. It makes no sense to make it configurable.

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.

Martin Roth 0fd0a054d4 Tyan S8226: Fix incompatible pointer warning
Fix warning:
  mptable.c:52, GNU Compiler 4 (gcc), Priority: Normal
  passing argument 3 of 'mptable_write_buses' from incompatible pointer type [enabled by default]

mptable_write_buses is expecting a pointer to an int, so I changed the
U8 isa_bus to an int to match.  A U8 doesn't make sense if the value could
be greater than 255 - certainly unlikely, but possible since the value
of isa_bus gets set to the maximum PCI bus number + 1.

Martin Roth 510171e23b Tyan S8226: Fix integer truncated warning
Fix Warning:
  sb700_cfg.c:129, GNU Compiler 4 (gcc), Priority: Normal
  large integer implicitly truncated to unsigned type [-Woverflow]

The issue here was that an 8 bit value was being placed into a 2-bit
bitfield.

    $ more src/vendorcode/amd/cimx/sb700/SBTYPE.h
    […]
    UINT32  AzaliaSdin0     :2;                     //6
    UINT32  AzaliaSdin1     :2;                     //8
    UINT32  AzaliaSdin2     :2;                     //10
    UINT32  AzaliaSdin3     :2;                     //12
    $ more src/mainboard/tyan/s8226/sb700_cfg.h
    […]
     *  SDIN0 is define at BIT0 & BIT1
     *   00 - GPIO PIN
     *   01 - Reserved
     *   10 - As a Azalia SDIN pin
     *  SDIN1 is define at BIT2 & BIT3
     *  SDIN2 is define at BIT4 & BIT5
     *  SDIN3 is define at BIT6 & BIT7
     */
    #ifndef AZALIA_SDIN_PIN
    #define AZALIA_SDIN_PIN              0x2A
    #endif
    […]
    $ more src/mainboard/tyan/s8226/sb700_cfg.c
    […]
    	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.

obvious this is a simple copy & paste error where someone just forgot
to change one occurrance of the GPIO nr. Also the AMD Inagua
schematics show that GPIO02 is what they really meant.

Also forward the fix to boards copied from Inagua (AMD South
Station, Union Station, Asrock E350M1).
