7f822a3368 libpayload/x86: Add x86-64 support to rdtsc()
This patch adds support for x86-64 to the rdtsc() function, allowing
it to correctly read the Time Stamp Counter (TSC) on both 32-bit and
64-bit x86 architectures.

BUG=b:242829490, b:351851626
TEST=Builds and boots on google/rex0 and google/rex64 systems and
manually verified correct TSC readings on x86-32 and x86-64 hardware.

afa39105d8 libpayload: Add x86_64 (64-bit) support
This patch introduces x86_64 (64-bit) support to the payload, building
upon the existing x86 (32-bit) architecture. Files necessary for 64-bit
compilation are now guarded by the `CONFIG_LP_ARCH_X86_64` Kconfig
option.

b3e336c51d treewide: Move stdlib.h to commonlib
This patch moves commonlib/stdlib.h -> commonlib/bsd/stdlib.h, since
all code is BSD licensed anyway.
It also moves some code from libpayloads stdlib.h to
commonlib/bsd/stdlib.h so that it can be shared with coreboot. This is
useful for a subsequent commit that adds devicetree.c into commonlib.

Also we don't support DMA on arm platforms in coreboot (only libpayload)
therefore `dma_malloc()` has been removed and `dma_coherent()` has been
moved to architecture specific functions. Any architecture that tries to
use `dma_coherent()` now will get a compile time error. In order to not
break current platforms like mb/google/herobrine which make use of the
commonlib/storage/sdhci.c controller which in turn uses `dma_coherent` a
stub has been added to arch/arm64/dma.c.

06e3dcac45 cbfs: Remove broken remnants of PAYLOAD_INFO feature
PAYLOAD_INFO is a very old feature that can add a key/value information
section to a payload file. It seems to have only ever been generated by
coreinfo and never really read by anything.

Since CB:1721 in 2012, the feature has been inadvertently broken in
practice since the `.note.pinfo` sections that contain the information
get discarded from the payload before cbfstool gets to see them. Since
CB:28647 in 2018, support for the section in the SELF loader was
(inadvertently?) dropped, so if someone actually fed cbfstool a payload
ELF that did have a `.note.pinfo` section, modern coreboot would refuse
to boot the payload entirely (which is probably not a good state to
leave things in).

This patch removes the code to generate PAYLOAD_INFO entries entirely,
but leaves the support to parse and extract those sections from old
payloads in place in cbfstool.

5ec3deac6b libpayload: timer: Revert timer_hz() return type to 64-bits
It seems that reducing the return type of timer_hz() to uint32_t in
CB:78888 was a bad idea... some Intel platforms actually use their raw
CPU clock for the timestamp counter which can be higher than 4GHz. This
patch reverts it back to uint64_t.

Also remove the redundant assertion in timer/generic.c since timer_us()
itself already does that check.

790b5cf442 {commonlib, libpayload}: Add "has_external_display" in coreboot table
This patch introduces a new coreboot table entry named
"has_external_display" to understand if external display is attached.

This information is useful to prevent graceful shutdown by payload
when the LID is closed but an external display is present.

This piece of the information will be gathered by coreboot and passed
into the payload using this new entry aka external_display because
payload (i.e., deptcharge) doesn't have any other way to determine
if external display is available.

d96ca24652 cbfs/vboot: Adapt to new vb2_digest API
CL:3825558 changes all vb2_digest and vb2_hash functions to take a new
hwcrypto_allowed argument, to potentially let them try to call the
vb2ex_hwcrypto API for hash calculation. This change will open hardware
crypto acceleration up to all hash calculations in coreboot (most
notably CBFS verification). As part of this change, the
vb2_digest_buffer() function has been removed, so replace existing
instances in coreboot with the newer vb2_hash_calculate() API.

Due to the circular dependency of these changes with vboot, this patch
also needs to update the vboot submodule:

cb28d649ea x86/cache.c: Implement dcache_*
A new ChromeOS automated test will be introduced to check the cbmem log
of diagnostic boot mode. Because the diagnostic boot does not allow
booting into kernel, the test must perform AP reset and then check the
cbmem log afterwards. However, the memory content might not be written
back to memory (from CPU cache) during AP reset because of the cache
snooping mechanism on x86. Hence, some API to flush cache is needed.

Implement dcache_* to allow flushing cache proactively in x86. To avoid
unnecessary flush, check dma_coherent before calling dcache_* functions,
which will be always true in x86. Therefore, this change won't affect
the original functionality.

23d2465720 commonlib: Clean up compiler.h
This patch contains several minor cleanups related to compiler.h:

- Replace __always_unused() (which is a Linux-specific concept that
  doesn't make sense without also having __maybe_unused(), and had zero
  uses in the codebase) with __unused() which moves here from helpers.h

- Add __underscores__ to the names of all attributes in the compiler
  attribute shorthand macros. This is necessary to make them work in
  files where the same name was already used for an identifier (e.g.
  cbfstool/cbfs.h's `unused` array of file types).

- Remove libpayload's own copy of compiler.h and make it directly pull
  in the commonlib/bsd copy.

69cc557cfb commonlib/bsd: Remove cb_err_t
cb_err_t was meant to be used in place of `enum cb_err` in all
situations, but the choice to use a typedef here seems to be
controversial. We should not be arbitrarily using two different
identifiers for the same thing across the codebase, so since there are
no use cases for serializing enum cb_err at the moment (which would be
the primary reason to typedef a fixed-width integer instead), remove
cb_err_t again for now.

db29b3765b libpayload: Fix legacy CBFS code after recent refactoring
The goal when adding the new CBFS API in CB:59497 was that the old CBFS
code would be left completely untouched and just moved to the side a
bit, so that it could continue to work for the payloads that use it
until they all have time to transition to the new CBFS API.
Unfortunately, between the different iterations of the patch something
went wrong with that and the final committed version of cbfs_legacy.c
does differ in some parts from the original code, including a changed
macro definition that breaks decompression support. This patch restores
all the legacy CBFS files to exactly what they used to be (other than
the necessary changes in cbfs_core.h to avoid double definition
clashes).
