This was breaking the build on OS X, but also wasn't working correctly
under linux anymore either. It wouldn't print the illegal symbols
when it failed.
- Split the generation of the offenders file from the actual check for
offending symbols and just send all output to /dev/null.
- Rewrite the check for offending symbols in a way that works with OS X.
Tested by adding a global variable to romstage and verifying the
failure is shown correctly. Verified that it works correctly with no
illegal variables.

When enabling the IOMMU on certain systems dmesg is spammed with I/O page faults like the following:
AMD-Vi: Event logged [IO_PAGE_FAULT device=00:14.0 domain=0x000a address=0x000000fdf9103300 flags=0x0030]
Decoding the faulting address:
0x000000fdf9103300
fdf91x Hypertransport system management region
33 SysMgtCmd (System Management Command) = 0x33
3 Base Command Type = 0x3: STPCLK (Stop Clock request)
3 SMAF (System Management Action Field) = [3:1] = 0x1
1 Signal State Bit Map = [0] = 0x1
Therefore, the error appears to be triggered by an upstream C1E request.
This was eventually traced to concurrent access to the SP5100's SPI Flash controller by
multiple APs during startup. Calls to the nvram read functions get_option and read_option
call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash
controller, thus placing the SP5100 in an invalid state. This limitation is not documented
in any public AMD errata, and was only discovered through considerable debugging effort.

This is implemented by adding a cbfs_locator object which

We currently race in SMM init on Atom 230 (and potentially
other CPUs). At least on the 230, this leads to a hang on
RSM, likely because both hyperthreads mess around with
SMBASE and other SMM state variables in parallel without
coordination. The same behaviour occurs with Atom D5xx.
Change it so first APs are spun up and sent to sleep, then
BSP initializes SMM, then every CPU, one after another.
Only do this when SERIALIZE_SMM_INITIALIZATION is set.
Set the flag for Atom CPUs.

This patch adds CC6 power save support to the AMD Family 15h
support code. As CC6 is a complex power saving state that
relies heavily on CPU, northbridge, and southbridge cooperation,
this patch alters significant amounts of code throughout the
tree simultaneously.
Allowing the CPU to enter CC6 allows the second level of turbo
boost to be reached, and also provides significant power savings
when the system is idle due to the complete core shutdown.

When we first added ARM support to coreboot, it was clear that the
bootblock would need to do vastly different tasks than on x86, so we
moved its main logic under arch/. Now that we have several more
architectures, it turns out (as with so many things lately) that x86 is
really the odd one out, and all the others are trying to do pretty much
the same thing. This has already caused maintenance issues as the ARM32
bootblock developed and less-mature architectures were left behind with
old cruft.
This patch tries to address that problem by centralizing that logic
under lib/ for use by all architectures/SoCs that don't explicitly
opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option).
This works great out of the box for ARM32 and ARM64. It could probably
be easily applied to MIPS and RISCV as well, but I don't have any of
those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and
leave that for later cleanup.

To support x86 verstage one needs a working buffer for
vboot. That buffer resides in the cache-as-ram region
which persists across verstage and romstage. The current
assumption is that verstage brings cache-as-ram up
and romstage tears cache-as-ram down. The timestamp,
cbmem console, and the vboot work buffer are persistent
through in both romstage and verstage. The vboot
work buffer as well as the cbmem console are permanently
destroyed once cache-as-ram is torn down. The timestamp
region is migrated. When verstage is enabled the assumption
is that _start is the romstage entry point. It's currently
expected that the chipset provides the entry point to
romstage when verstage is employed. Also, the car_var_*()
APIs use direct access when in verstage since its expected
verstage does not tear down cache-as-ram. Lastly, supporting
files were added to verstage-y such that an x86 verstage
will build and link.

The code flow doesn't fall through to walkcbfs, as it does in the rest
of bootblock.S. Instead, walkcbfs is called (albeit via a jmp). The
linker cannot know this when walkcbfs.S is included directly.
When we use a CAR bootblock, we lose several hundred bytes because
walkcbfs is not garbage-collected, yet it isn't used. This problem
is solved by assembling walkcbfs.S separately, and linking it.

The x86 bootblock linking is a mess. The bootblock is treated in
a very special manner, and never received the update to link-time
garbage collection.
On newer x86 platforms, the boot media is no longer memory-mapped.
That means we need to do a lot more setup in the bootblock. ROMCC is
unsuitable for this task, and walkcbfs only works on memory-mapped
CBFS. We need to revise the x86 bootflow for this new case.
The approach this patch series takes is to perform CAR setup in the
bootblock, and load the following stage (either romstage or verstage)
from the boot media. This approach is not new, but has been done on
our ARM ports for years.
Since we will be adding .c files to the bootblock, it is prudent to
use link-time garbage collection. This is also consistent to how we
do things on other architectures. Unification FTW!

In order to do a verification of romstage on x86 one needs to
run verstage which verifies romstage (and the memory init code).
However, x86 doesn't have SRAM like every other modern SoC so
managing the cache-as-ram region is especially critical.
First move all of the "shared" objects to the beginning of
the .car.data section. This change then ensures that each stage
using car.ld to link has the same consistent view of the addresses
of these fixed-sized objects in cache-as-ram. The CAR_GLOBALs can
be unique per stage. However, these variables are expected to have
a value of zero at the start of each stage. In order to allow a
stage to provide those semantics outside of the initial cache-as-arm
setup routine add _car_global_start and _car_global_end symbols.
Those symbols can be used to clear the CAR_GLOBALs for that stage.
Note that the timestamp region can't be moved out similarly to the
pre-ram cbmem console because the object storage of the timestamp
cache is used *after* cache-as-ram is torn down to indicate if the
cache should be used or not. Therefore, that timestamp needs to
migrated to ram. A logic change in src/lib/timestamp.c could
alleviate this requirement, but that task wasn't tackled in this
patch.

Previously, the x86 romstage build process was unconditionally
creating a romstage.inc and adding it to crt0s. This step is
inherently not necessary in the !ROMCC case becaue the romstage.inc
was created by the compiler outputting assembler. That means
MAINBOARDDIR/romstage.c is truly a C environment that requires
some sort of assembler stub to call into (cache_as_ram.inc from
the chipset dirs). Therefore, remove this processing. The result
is that MAINBOARDDIR/romstage.c can use the normal build steps
in creating an object and linking. The layout of romstage.elf
will change but that's only from a symbol perspective.

In order to accommodate tracking timestamps in all the
__PRE_RAM__ stages (bootblock, verstage, romstage, etc)
of a platform one needs to provide a way to specify
a persistent region of SRAM or cache-as-ram to store
the timestamps until cbmem comes online. Provide that
infrastructure.

The option --divide is required by our assembler to ensure that
'/' is not parsed as a comment sign but as a division, because
some of the cache as ram code is using divisions.
The --divide parameter has been part of the GNU as since binutils 2.17.
Hence, compile romstage (which contains cache as ram init) with
-Wa,--divide unconditionally instead of probing for it and adding it to
all compiler invocations (because that is causing random trouble with
clang when compiling the SMM code and calling gcc with --divide instead of
-Wa,--divide)

The SMBIOS Specification 2.3 and up defines Maximum Structure Size
as the "Size of the largest SMBIOS structure, in bytes, and encompasses
the structure’s formatted area and text strings." The hardcoded size
is too small to accurately represent the maximum SMBIOS structure sizes.
While the field is not used by Linux it is used by some RTOS
implementations, eg. VxWorks.
TEST=Booted Linux and ran github.com/bfrisch/dmidecode which verified
the maximum structure size on Minnowboard Max.

Squashed and adjusted two changes from chromium.git. Covers
CBMEM init for ROMTAGE and RAMSTAGE.
cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API
There are several use cases for performing a certain task when CBMEM is
first set up (usually to migrate some data into it that was previously
kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them
differently: timestamp migration is called explicitly from
cbmem_initialize(), certain x86-chipset-specific tasks use the
CAR_MIGRATION() macro to register a hook, and the CBMEM console is
migrated through a direct call from romstage (on non-x86 and SandyBridge
boards).
This patch decouples the CAR_MIGRATION() hook mechanism from
cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer
description of what it really does. All of the above use cases are
ported to this new, consistent model, allowing us to have one less line
of boilerplate in non-CAR romstages.
BRANCH=None
BUG=None
TEST=Built and booted on Nyan_Blaze and Falco with and without
CONFIG_CBMEM_CONSOLE. Confirmed that 'cbmem -c' shows the full log after
boot (and the resume log after S3 resume on Falco). Compiled for Parrot,
Stout and Lumpy.

cbmem: Extend hooks to ramstage, fix timestamp synching
Commit 7dd5bbd71 (cbmem: Unify random on-CBMEM-init tasks under common
CBMEM_INIT_HOOK() API) inadvertently broke ramstage timestamps since
timestamp_sync() was no longer called there. Oops.
This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism
to the cbmem_initialize() call in ramstage. The macro is split into
explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as
possible and prevent surprises (although just using a single macro and
relying on the Makefiles to link an object into all appropriate stages
would also work).
This allows us to get rid of the explicit cbmemc_reinit() in ramstage
(which I somehow accounted for in the last patch without realizing that
timestamps work exactly the same way...), and replace the older and less
flexible cbmem_arch_init() mechanism.
Also added a size assertion for the pre-RAM CBMEM console to memlayout
that could prevent a very unlikely buffer overflow I just noticed.
BRANCH=None
BUG=None
TEST=Booted on Pinky and Falco, confirmed that ramstage timestamps once
again show up. Compile-tested for Rambi and Samus.

This patch adds a few bit counting functions that are commonly needed
for certain register calculations. We previously had a log2()
implementation already, but it was awkwardly split between some C code
that's only available in ramstage and an optimized x86-specific
implementation in pre-RAM that prevented other archs from pulling it
into earlier stages.
Using __builtin_clz() as the baseline allows GCC to inline optimized
assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and
to perform constant-folding if possible. What was previously named log2f
on pre-RAM x86 is now ffs, since that's the standard name for that
operation and I honestly don't have the slightest idea how it could've
ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm
with Float result, whereas the Find First Set operation has no direct
correlation to logarithms that I know of). Make ffs result 0-based
instead of the POSIX standard's 1-based since that is consistent with
clz, log2 and the former log2f, and generally closer to what you want
for most applications (a value that can directly be used as a shift to
reach the found bit). Call it __ffs() instead of ffs() to avoid problems
when importing code, since that's what Linux uses for the 0-based
operation.
CQ-DEPEND=CL:273023
BRANCH=None
BUG=None
TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new
log2() and __ffs() results on Falco for a bunch of test values.
