This reverts commit 4f13f72dbc ("libpayload: Define UCHAR_MAX/CHAR_MIN/CHAR_MAX").
Reason for revert: char can be either signed or unsigned. If it's
unsigned, then CHAR_MIN would be incorrectly defined as 128.

This commit adds a new coreboot table, CB_TAG_BOOT_MODE, to pass
platform boot mode information to the payload.
The new table defines flags for low-battery mode and off-mode charging,
which are essential for a payload to properly initialize the charger
driver.
The cb_parse_boot_mode function is added to read this information, and
the sysinfo_t structure is updated to store the parsed boot mode data.
This ensures that the payload can accurately determine the system's
power state at boot and payload operations are also in sync with the
boot firmware.
The following scenarios were tested and verified:
Scenario 1: Low-battery, no charger
- coreboot detects the low-battery state and performs an immediate
shutdown after displaying the low-battery splash screen.
Scenario 2: Low-battery, charger attached
- coreboot detects the low-battery state but continues booting because
a charger is present. The payload receives the low-battery
information (using the same source as coreboot) and correctly
initiates the charging process.
Scenario 3: Off-mode charging
- The system boots directly from an S5 state due to a charger being
plugged in. coreboot detects the off-mode state, skips the firmware
splash screen, and hands off control to the payload, which then
starts charging.
Scenario 4: Normal boot
- The system boots without any low-battery or off-mode conditions.
coreboot and the payload both detect a normal boot (using the same
information), bypass charging initialization, and proceed to boot the
operating system.
TEST=Able to build and boot on google/quenbi device and verify the boot
mode flag is correctly passed.

This commit extends libpayload's understanding of SPI flash devices by
adding a flags field to both struct cb_spi_flash and struct
sysinfo_t.spi_flash.
The new CB_SPI_FLASH_FLAG_IN_4BYTE_ADDR_MODE flag will be populated
from the coreboot table's lb_spi_flash entry. This allows payloads to
reliably determine if the SPI flash is currently configured for 4-byte
addressing, enabling more robust flash operations without needing to
re-probe or re-enforce the mode.
Note: `erase_cmd` type was changed from uint32_t to uint8_t. This is
because only the lowest byte of the original uint32_t was ever used.
The change ensures proper sizing, maintains compatibility with older
coreboot tables, and makes the remaining space available for new fields.

On arm64 device libpayload reserves 32MB of space for the DMA allocator.
DMA allocators are usually just used for small bounce buffers or DMA
descriptors for SPI, I2C or USB transfers, nothing that should get
anywhere near the size of megabytes.
Presumably the original number was just made arbitrarily large because
it didn't matter. But more recently we have had security applications
(guarding secrets that get received over SPI/I2C from firmware and must
not be visible to the OS after handoff) that made us want to erase the
entire DMA heap just to be sure no driver left a copy of any secret
lying around there. This means the size is no longer fully harmless
because erasing a larger heap takes more time.
Change the default to 1MB which should still be more than more than
enough for any real applications, but should bring the time required to
erase it back into negligible territory.

Our mechanism to override the default (pure C) memory function
implementations (memset, memcpy, memmove) with architecture-specific
optimized assembly versions doesn't actually work: it turns out that
weak functions don't work as you'd naively expect when you pack them
together with a strong definition from a different object into a static
library. When a linker tries to resolve a symbol from a static library,
it just picks the first one it finds, even if it is weak. It doesn't
evaluate all objects in the library to see if there are other strong
definitions.
To fix this, this patch gets rid of the weak symbols and uses Kconfigs
instead. It adds an optimized memmove() implementation for x86 because
that makes things easier (then all architectures either override all
three functions or none of them). Also remove memcmp() from the
functions that can be overridden for now because nobody ever needed that
anyway.

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.

Use C99 flexible arrays instead of older style of one-element or
zero-length arrays.
It allows the compiler to generate errors when the flexible array does
not occur at the end in the structure.

`stddef.h` should only provide the definitions defined by ISO or Posix.
The included `commonlib/bsd/helpers.h` provide a lot of non standard
definitions that may interfere with definitions from the application.

Only edk2 used this to fill in a different struct but even there the
entries go unused, so removing this struct element from coreboot has
no side effects.

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:
Updating from commit id 18cb85b5:
2load_kernel.c: Expose load kernel as vb2_api
to commit id b827ddb9:
tests: Ensure auxfw sync runs after EC sync

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.

Add commonlib/bsd/elog dependency in libpayload. This will allow other
payloads (e.g. depthcharge) to implement their own eventlog read and
write utilities.
Also include commonlib/bsd/elog.c source to libc-srcs. This ensure
payloads could utilize commonlib elog helper functions.

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.
