6a1210901d AMD RS780, SR5650: PcieTrainPort: Fix typo *i*gnoring in comment
Reading the paste of code in a message to the mailing list [1],
a typo was spotted and found in one more place.

    $ git grep egnoring
    src/southbridge/amd/rs780/cmn.c:                         * egnoring the reversal case
    src/southbridge/amd/sr5650/sr5650.c:                     * egnoring the reversal case

These typos are there since when the code was committed and are
now corrected.

573a1d6fa8 Persimmon/Fam14/SB800 DSDT: Split into common areas
Split the Persimmon DSDT into common code areas.
For example, split the Southbridge specific code into
the Southbridge directory and CPU specific code into
the CPU directory.  Also adding the superio.asl file
to the Persimmon DSDT tree. This file is empty for
the moment but will be necessary in the future.  I have
also emptied the thermal.asl file in the mainboard
directory because it does not seem to perform as
intended (fan control does not change when it is
brought back into the code base) and it has been
inside a '#if 0' statement for a long time.  Removing
it until it is decided that it is actually necessary.

This change was verified in three different ways:
	1. Visual comparison of the compiled DSDT pulled from the
	Persimmon after booting into Linux using the ACPI tools
	acpidump, acpixtract, and iasl.  The comparison was done
	between the DSDT before and after doing the split work.

	This test is somewhat difficult considering the expanse
	of the changes.  Blocks of code have been moved, and
	others changed.

	2. Linux logs were dumped before and after the DSDT split.
	Logs dumped and compared include dmesg and lspci -tv.
	Neither log changed significantly between the two compare
	points.

	3. The test suite FWTS was run on the Coreboot build both
	before and after doing the DSDT split with the command
	'sudo fwts -b -P -u'.  The flag -b specifies all batch jobs,
	-P specifies all power tests, and -u specifies utilities.
	Interactive jobs were not run as most of them consist of
	laptop checks.  Again, there were no significant changes
	between the two endpoints.

These tests lead me to believe that there was no change in
the functionality of the ACPI tables apart from what is
known and expected.

This patch is the first of a series of patches to split the DSDT.
The ASRock patch was merged before this one and breaks the ASROCK
E350M1 build (patch 8d80a3fb: http://review.coreboot.org/#/c/3050/).

9c07c8f53d lynxpoint: Move ACPI NVS into separate CBMEM table
The ACPI NVS region was setup in place and there was a CBMEM
table that pointed to it.  In order to be able to use NVS
earlier the CBMEM region is allocated for NVS itself during
the LPC device init and the ACPI tables point to it in CBMEM.

The current cbmem region is renamed to ACPI_GNVS_PTR to
indicate that it is really a pointer to the GNVS and does
not actually contain the GNVS.

b39ba2efcf lynxpoint: Basic configuration of SerialIO devices
This adds configuration of SerialIO devices in the Lynxpoint-LP
chipset.  This includes DMA, I2C, SPI, UART, and SDIO controllers.

There is assorted magic setup necessary for the devices and
while it is similar for each device there are subtle differences
in some register settings.

These devices must be put into "ACPI Mode" in order to take
advantage of S0ix.  When in ACPI mode the allocated PCI BARs
must be passed to ACPI so it can be relayed to the OS.  When
the devices are in ACPI mode BAR0+BAR1 is saved into ACPI NVS
and then updated and returned when the OS calls _CRS.

Note that is is not entirely complete yet.  We need to update
the IASL compiler in our build environment to support ACPI 5.0
in order to be able to pass the FixedDMA entries to the kernel.
There are also no ACPI methods defined yet to do D0->D3->D0
transitions for actually entering/exiting S0ix states.

This is hard to test right now because our kernel does not support
any of these devices in ACPI mode.  I was able to build and test
the upstream bleeding-edge branch of the linux-pm git tree.  With
that tree I was able to enumerate and load the driver for the
DesignWare I2C driver and attempt to probe the I2C bus -- although
there are no devices attatched.

I am also able to see the resources from ACPI in /proc/iomem get
reserved properly in the kernel.

d6d6db3717 lynxpoint: fix enable_pm1() function
The new enable_pm1() function was doing 2 things wrong:

1. It was doing a RMW of the pm1 register. This means we were
   keeping around the enables from the OS during S3 resume. This
   is bad in the face of the RTC alarm waking us up because it would
   cause an infinite stream of SMIs.
2. The register size of PM1_EN is 16-bits. However, the previous
   implementation was accessing it as a 32-bit register.

The PM1 enables should only be set to what we expect to handle in the
firmware before the OS changes to ACPI mode.

af3158c0cf lynxpoint: split clearing and enabling of smm
Previously southbridge_smm_init() was provided that did both
the clearing of the SMM state and enabling SMIs. This is
troublesome in how haswell machines bring up the APs. The BSP
enters SMM once to determine if parallel SMM relocation is possible.
If it is possible the BSP releases the APs to do SMM relocation.
Normally, after the APs complete the SMM relocation, the BSP would then
re-enter the relocation handler to relocate its own SMM space.
However, because SMIs were previously enabled it is possible for an SMI
event to occur before the APs are complete or have entered the
relocation handler. This is bad because the BSP will turn off parallel
SMM save state. Additionally, this is a problem because the relocation
handler is not written to handle regular SMIs which can cause an
SMI storm which effectively looks like a hung machine. Correct these
issues by turning on SMIs after all the SMM relocation has occurred.

d2be1f11e1 AMD hudson & SB800 - Fix issues with mawk
When calculating the offsets of the various binary blobs within the
coreboot.rom file, we noticed that using mawk as the awk tool instead
of using gawk led to build issues.  This was finally traced to the
maximum value of the unsigned long variables within mawk - 0x7fff_ffff.
Because we were doing calculations on values up in the 0xffxxxxxx
range, these numbers would either be turned into floating point values
and printed using scientific notation, or truncated at 0x7fff_ffff.

To fix this, we print the values out as floating point, with no decimal
digits.  This works in gawk, mawk, and original-awk and as the testing
below show, seems to be the best way to do this.

printf %u 0xFFFFFFFF | awk '{printf("%.0f %u %d", $1 , $1 , $1 )}'
mawk:         4294967295 2147483647 2147483647
original-awk: 4294967295 2147483648 4294967295
gawk:         4294967295 4294967295 4294967295

The issue of %d not matching gawk and original-awk has been reported
to ubuntu.

In the future, I'd recommend that whenever awk is used, a format is
specified. It doesn't seem that we can count on the representation
being the same between the different versions.

fd79562915 romstage: add support for vboot firmware selection
This patch implements support for vboot firmware selection. The vboot
support is comprised of the following pieces:

1. vboot_loader.c - this file contains the entry point,
   vboot_verify_firmware(), for romstage to call in order to perform
   vboot selection. The loader sets up all the data for the wrapper
   to use.
2. vboot_wrapper.c - this file contains the implementation calling the vboot
   API. It calls VbInit() and VbSelectFirmware() with the data supplied
   by the loader.

The vboot wrapper is compiled and linked as an rmodule and placed in
cbfs as 'fallback/vboot'. It's loaded into memory and relocated just
like the way ramstage would be. After being loaded the loader calls into
wrapper. When the wrapper sees that a given piece of firmware has been
selected it parses firmware component information for a predetermined
number of components.

Vboot result information is passed to downstream users by way of the
vboot_handoff structure. This structure lives in cbmem and contains
the shared data, selected firmware, VbInitParams, and parsed firwmare
components.

During ramstage there are only 2 changes:

1. Copy the shared vboot data from vboot_handoff to the chromeos acpi
   table.
2. If a firmware selection was made in romstage the boot loader
   component is used for the payload.

Noteable Information:
- no vboot path for S3.
- assumes that all RW firmware contains a book keeping header for the
  components that comprise the signed firmware area.
- As sanity check there is a limit to the number of firmware components
  contained in a signed firmware area. That's so that an errant value
  doesn't cause the size calculation to erroneously read memory it
  shouldn't.
- RO normal path isn't supported. It's assumed that firmware will always
  load the verified RW on all boots but recovery.
- If vboot requests memory to be cleared it is assumed that the boot
  loader will take care of that by looking at the out flags in
VbInitParams.

Built and booted. Noted firmware select worked on an image with
RW firmware support. Also checked that recovery mode worked as well
by choosing the RO path.

24d1d4b472 x86: Unify arch/io.h and arch/romcc_io.h
Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.

Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

467f31de92 haswell/lynxpoint: Use new PCH/PM helper functions
This makes use of the new functions from pmutil.c that take
care of the differences between -H and -LP chipsets.

It also adds support for the LynxPoint-LP GPE0 register block
and the SMI/SCI routing differences.

The FADT is updated to report the new 256 byte GPE0 block on
wtm2/wtm2 boards which is too big for the 64bit X_GPE0 address
block so that part is zeroed to prevent IASL and the kernel
from complaining about a mismatch.

This was tested on WTM2.  Unfortunately I am still unable to get an
SCI delivered from the EC but I suspect that is due to a magic
command needed to put the EC in ACPI mode.  Instead I verified that
all of the power management and GPIO registers were set to expected
values.

I also tested transitions into S3 and S5 from both the kernel and
by pressing the power button at the developer mode screen and they
all function as expected.

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:

Baseline                          Alt
--------                          --------

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.

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.

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).

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.

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()

5079a0d32f Remove assembly coded log2 function
As we move to supporting other systems we need to get rid of assembly
where we can. The log2 function in src/lib is identical to the assembly
one (tested for all 32-bit signed integers :-) and takes about 10 ns
to run as opposed to 5ns for the non-portable assembly version. While speed
is good, I think we can spare the 15 ns or so we add to boot time
by using the C version only.

23f38cd05c Get rid of drivers class
The use of ramstage.a required the build system to handle some
object files in a special way, which were put in the drivers
class.

These object files didn't provide any symbols that were used
directly (but only via linker magic), and so the linker never
considered them for inclusion.

With ramstage.a gone, we can drop this special class, too.

so it can find the GSMI command in bits 7:0 but not the
extended command code in bits 15:8.

7f3d442abb SMM: Avoid use of global variables in SMI handler
Using global variables with the TSEG is a bad idea because
they are not relocated properly right now.  Instead make
the variables static and add accessor functions for the
rest of SMM to use.

At the same time drop the tcg/smi1 pointers as they are
not setup or ever used.  (the debug output is added back
in a subsequent commit)

to a separate function and make it a bit more versatile with the
checks it does to find a match so it can be used in other

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.
