ae532fe641 payloads/libpayload: Add fast data types to types.h
libpayload stdint.h only supports typedefs for datatypes of exact
bits. This makes libpayload less flexible to support libraries
that reference different data types.

Add fast data types in types.h.

a8139c0b87 treewide: Rename PM4LE -> PML4E

It is annoying when searching for the wrong abbreviation in the spec so
fix it everywhere it occurs.

ba3af158aa libpayload: Unify selfboot() implementations
selfboot() doesn't really need to be architecture dependent. All
architectures are essentially doing the same thing with a normal
function call, only x86_32 needs an extra attribute. arm64 and x86 also
previously haven't been passing the coreboot table pointer, even though
they should. This patch fixes that.

e5cce00552 libpayload: Remove default empty implementations in mock cache.h
The mock/arch/cache.h file exists for libpayload unit tests. However,
the default implementations (as empty macros) in it make these functions
difficult to mock in unit tests.

Therefore, we follow what's done for mock/arch/io.h, by only including
function declarations in the header. Each test is expected to implement
mocks for these cache functions when required.

0dcdc0347c commonlib/bsd: Add strlen() and strnlen() functions
Add strlen() and strnlen() to commonlib/bsd by rewriting them from
scratch, and remove the same functions from coreboot and libpayload.

Note that in the existing libpayload implementation, these functions
return 0 for NULL strings. Given that POSIX doesn't require the NULL
check and that other major libc implementations (e.g. glibc [1]) don't
seem to do that, the new functions also don't perform the NULL check.

ea6b6acd01 soc/intel/cmn/cse: Refactor CBMEM ID handling for flexibility
This patch refactors the handling of CSE CBMEM IDs to enable platforms
to choose whether to perform CSE sync operations within coreboot or
defer it to the payload. This separation improves code organization,
ensuring `cse_lite.c` focuses on coreboot-specific CSE Lite tasks.

Now, platforms can select:
  * `SOC_INTEL_CSE_LITE_SKU` for CSE sync within coreboot
  * `SOC_INTEL_CSE_LITE_SYNC_BY_PAYLOAD` for deferred payload sync

This change ensures mutually exclusive options, avoiding unnecessary
SPI flash size increases.

6643b5e374 libpayload/arm64: Support FEAT_CCIDX
ARM SoC supports FEAT_CCIDX after ARMv8.3. The register field
description of CCSIDR_EL1 is different when FEAT_CCIDX is implemented.
If numsets and associativity from CCSIDR_EL1 are not correct, the system
would hang during mmu_disable().

Rather than assuming that FEAT_CCIDX is not implemented, this patch
adds a check to dcache_apply_all to use the right register format.

Reference:
- https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/12770

BUG=b:317015456
TEST=mmu_disable works on the FEAT_CCIDX supported SoC.

6b4522e2aa libpayload: gdb: Make die_if() format string a literal
CB:77969 made minor changes to the die_if() macro. One of the
consequences is that the format string passed to it can no longer be a
real `char *` variable, it needs to actually be a string literal. In the
vast majority of call sites that is already the case, but there was one
instance in the GDB code where we're reusing the same format string many
times and for that reason put it into a const variable. Fix that by
turning it into a #define macro instead. (Even though this technically
duplicates the format string, the linker is able to merge identical
string literals together again, so it doesn't really end up taking more
space.)

c00c14077d libpayload: Make GPL commonlib includes available to payloads and tests
CB:77968 made some non-BSD commonlib files part of libpayload when
CONFIG_LP_GPL is set. This patch exports those headers to the payload
(again only when CONFIG_LP_GPL is set) so that payloads can also call
the functions in them directly.

Also make those includes available to tests so that their functions can
be tested. There's no menuconfig for unit tests, so they are included
unconditionally, but this should be fine since the tests are standalone
and won't have to link with any proprietary third-party code.

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.

This patch passes the correct flag to vboot to enable SIMD crypto
acceleration on arm64 devices. This uses a core part of the ISA and
should thus be supported on all arm64 SoCs -- so we normally always
want it enabled, but there should still be a Kconfig in case a SoC wants
to use the hwcrypto interface for its own (off-CPU) crypto acceleration
engine instead. (You could also disable it to save a small amount of
code size at the cost of speed, if necessary.)
