As commented by Aaron Durbin, a separate `pch_enable_acpi()` is
not needed: “The existing code path *in this file* is about enabling
the io apic.” [1].

Paul Menzel 42409e8732 northbridge/amd/amdmct: Use `static const` instead of `const static`
From ISO C99 standard: »The placement of a storage-class specifier
other than at the beginning of the declaration specifiers in a
declaration is an obsolescent feature.«

Found at <http://www.approxion.com/?p=41>.

The following command was used to make the change.

    $ git grep -l 'const static' src/ | xargs sed -i 's/const static/static const/'

As asked by Bruce Griffith, the changes in `src/vendorcode` were
reverted as that is what AMD prefers.

The same change was done already for AMD Persimmon in the following
commit.

Gabe Black 3aa58162e1 am335x: Clean up/fix some settings in the am335x Kconfig.
Some settings in the am335x Kconfig weren't actually used for anything, some
where place holders, and some where left over from another CPU. The memory
addresses are in the internal RAM in the SOC as described in the reference
manual. The stack is put where the internal ROM had its stack, and the
bootblock is put at the bottom of that region as the manual suggests. The
ROM stage offset is set to 10K which is a bit bigger than the ~7.5K the
bootblock currently takes up.

Steven Sherk 474eeedbc8 AMD Trinity boards: Add reserved memory area for SPI base address in ACPI
- SPI controller base address gets overwritten by SD controller under Linux.

    - Reason for overwrite is the SPI base address isn't in a standard BAR and doesn't
      get automatically reserved. Solution is to add it as a reserved memory area in
      ACPI.

    - This issue was found on the ASUS F2A85-M platform. Currently a workaround on this
      platform was made as part of: http://review.coreboot.org/#/c/3167/3

    - Once approved a follow-on patch for other southbridges using a non-standard BAR for
      the spi controller.

Siyuan Wang 0390112407 AMD Parmer: fix issue 'S3 fails to suspend after wake up from USB keyboard'
This issue can be reproduced in Linux by the following steps:
1) use pm-suspend to suspend.
2) use USB keyboard to wake up.
3) use pm-suspend to suspend. FAIL To SUSPEND.

The cause of this issue is:
USB devices use bit 11(0x0b) of GP0_STS represents S3 wake up event,
but this bit is not clear after wake up. So OS thinks there is a
wake up signal and wake up immediately.

In this patch, I add AcpiGpe0Blk using MMIO access and write 1
on bit 11. I have tested on Parmer.

elements is error prone and unnecessary.

Rudolf Marek’s patch »ASUS F2A85-M: Correct and clean up PCIe

»Not sure why the copy is needed instead of direct reference.

Ronald G. Minnich b460a66aa9 Get buildgcc to behave reasonably with the -p choice.
buildgcc has many wrong choices, and two right ones,
but you would never guess that. It's even more
frustrating when it spends lots of time building a
full tool chain and you find out it's not the one you
wanted and, still worse, you've forgotten what it does want
and, even worse, it won't f-ing tell you what the two
right choices are!.

Have it tell you when you've done something wrong, and have it
make reasonable decisions when you say things like
-p arm
instead of
-p armv7a-eabi

This change lowers my blood pressure 10 points.

Paul Menzel 51837f9dac Intel Sandy Bridge: udelay.c: Change comparison from <= to <
Currently code in `udelay.c` differs between the Intel northbridges
GM45, 945 on the one hand and Sandy Bridge on the other hand.

The reason for this is that a wrong comparison > was used.

Paul Menzel b2cddd4c12 ASUS F2A85-M: romstage.c: Set RAM voltage for non 1.5 Volt case
Currently the code in the if statement

    if (!byte)
    	do_smbus_write_byte(0xb20, 0x15, 0x3, byte);

only gets executed if `byte == 0x0`, that means only in the
default case where RAM voltage is 1.5 Volts. But the RAM voltage
should be changed when configured for the non-default case.

So negate the predicate to alter the RAM voltage for the
non-default cases.

To prevent the build error

add `southbridge/amd/agesa/hudson/smbus.c` providing the function
`do_smbus_write_byte` to ROM stage in `Makefile.inc`. That can
actually be used after the needed header files are included in a

cbmemc_reinit() no longer needs to be called from romstage

However, the cbmem_console_p is referenced using the
cache-as-ram API. When cbmem is initialized the console
is automatically copied over by calling cbmemc_reinit()
through a callback.

Aaron Durbin 716738a6b8 x86: add cache-as-ram migration option
There are some boards that do a significant amount of
work after cache-as-ram is torn down but before ramstage
is loaded. For example, using vboot to verify the ramstage
is one such operation. However, there are pieces of code
that are executed that reference global variables that
are linked in the cache-as-ram region. If those variables
are referenced after cache-as-ram is torn down then the
values observed will most likely be incorrect.

Therefore provide a Kconfig option to select cache-as-ram
migration to memory using cbmem. This option is named
CAR_MIGRATION. When enabled, the address of cache-as-ram
variables may be obtained dynamically. Additionally,
when cache-as-ram migration occurs the cache-as-ram
data region for global variables is copied into cbmem.
There are also automatic callbacks for other modules
to perform their own migration, if necessary.

Dave Frodin adc300d88b libpayload: Fix the logic for hardware-less serial consoles
This fixes the configuration where serial console output is
being sent to non-existant hardware to be captured with I/O
trapping. In this configuration where there isn't serial
hardware present we still want to init the consoles. We just
never want to read non-existant hardware.

Ronald G. Minnich 4bd7b0cbad EXYNOS5250/SNOW: fix the build script. Add a script to get the bl1.
build-snow got broken when the snow makefile improved. So fix it.

While we're at it, create a script like the update-microcode
scripts that gets the bl1. I thought about making this a common
script but the various names and paths always evolve, leaving
me thinking it's not worth it. This script is just a
piece of the snow build script.

Paul Menzel 3a1457137e AMD Fam15tn boards: BiosCallOuts.c: Declare codec arrays as `static`
These arrays are declared as `static` for AMD SB800 based boards,
so do the same for this generation.

Rudolf Marek just changed `const CODEC_TBL_LIST` to `static const`
in [1]. Adapt all Fam15tn based boards (AMD Parmer, AMD Thatcher,
ASUS F2A85-M) to keep the differences between them small.

Aaron Durbin 38c326d041 x86: add thread support
Thread support is added for the x86 architecture. Both
the local apic and the tsc udelay() functions have a
call to thread_yield_microseconds() so as to provide an
opportunity to run pending threads.

Aaron Durbin 4409a5eef6 coreboot: add thread cooperative multitasking
The cooperative multitasking support allows the boot state machine
to be ran cooperatively with other threads of work. The main thread
still continues to run the boot state machine
(src/lib/hardwaremain.c).  All callbacks from the state machine are
still ran synchronously from within the main thread's context.
Without any other code added the only change to the boot sequence
when cooperative multitasking is enabled is the queueing of an idlle
thread. The idle thread is responsible for ensuring progress is made
by calling timer callbacks.

The main thread can yield to any other threads in the system. That
means that anyone that spins up a thread must ensure no shared
resources are used from 2 or more execution contexts. The support
is originally intentioned to allow for long work itesm with busy
loops to occur in parallel during a boot.

Note that the intention on when to yield a thread will be on
calls to udelay().
