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.

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.

It seems that we have some applications where we need to calculate a GCD
in 64 bits. Now, we could instantiate the algorithm multiple times for
different bit width combinations to be able to use the most efficient
one for each problem... but considering that the function usually only
gets called once per callsite per stage, and that software emulation of
64-bit division on 32-bit systems doesn't take *that* long either, we
would probably usually be paying more time loading the second instance
of the function than we save with faster divisions. So let's just make
things easy and always do it in 64-bit and then nobody has to spend time
thinking on which version to call.

This patch moves the IP checksum algorithm into commonlib to prepare for
it being shared with libpayload. The current implementation is ancient
and pretty hard to read (and does some unnecessary questionable things
like the type-punning stuff which leads to suboptimal code generation),
so this reimplements it from scratch (that also helps with the
licensing).
This algorithm is prepared to take in a pre-calculated "wide" checksum
in a machine-register-sized data type which is then narrowed down to 16
bits (see RFC 1071 for why that's valid). This isn't used yet (and the
code will get optimized out), but will be used later in this patch
series for architecture-specific optimization.

Having a separate romstage is only desirable:
- with advanced setups like vboot or normal/fallback
- boot medium is slow at startup (some ARM SOCs)
- bootblock is limited in size (Intel APL 32K)
When this is not the case there is no need for the extra complexity
that romstage brings. Including the romstage sources inside the
bootblock substantially reduces the total code footprint. Often the
resulting code is 10-20k smaller.
This is controlled via a Kconfig option.

This commit resolves this potential NULL-pointer dereference by
passing the pointer systematically and without affecting the logic as

PSR data is created and stored in CSE data partition. In platforms that
employ CSE Lite SKU firmware, a firmware downgrade involves clearing of
CSE data partition which results in PSR data being lost. In order to
backup PSR data before initiating firmware downgrade, CSE Lite firmware
supports a command to do this. This command works only after memory has
been initialized. So the CSE firmware downgrade can be done only in
post-RAM stage. CSE firmware sync actions will be moved to early
ramstage to support this.
Moving CSE firmware sync actions to ramstage results in cse_get_bp_info
command taking additional boot time of ~45-55ms. To avoid this,
cse_get_bp_info will be sent in early romstage and the response will be
stored in cbmem to avoid sending the command again, and re-use in
ramstage.
This patch adds a CBMEM ID to store this CSE Boot Partition Info
response in cbmem.

Intel Meteor Lake SOC has a separate I/O Expander (IOE) die.
SRAM from this IOE die contains crashlog records for the IPs
of the IOE die.
This patch adds functions with empty implementation using
__weak attribute for IOE die related crashlog, changes common
data structures while maintaining backwards compatibility,
and support for filling IOE crashlog records, guarded by
SOC_INTEL_IOE_DIE_SUPPORT config and makes cl_get_pmc_sram_data
function as weak because it needs SOC specific implementation.
Bug=b:262501347
TEST=Able to build. With Meteor Lake SOC related patch, able to
capture and decode crashlog

The patch implements an API that stores the CSE firmware version in the
CBMEM table. The API will be called from RAMSTAGE based on boot state
machine BS_PRE_DEVICE/BS_ON_EXIT
Additionally, renamed ramstage_cse_fw_sync() to ramstage_cse_misc_ops()
in order to add more CSE related operations at ramstage.
This patch also adds a configuration option,
'SOC_INTEL_STORE_CSE_FPT_PARTITION_VERSION', which enables the storage
of firmware version information in CBMEM memory. This information can be
used to identify the firmware version that is currently installed on the
system. The option depends on the `DRIVERS_INTEL_ISH` config and
platform should be flexible enough to opt out from enabling this
feature.
The cost of sending HECI command to read the CSE FPT is significant
(~200ms) hence, the idea is to read the CSE RW version on every cold
reset (to cover the CSE update scenarios) and store into CBMEM to
avoid the cost of resending the HECI command in all consecutive warm
boots.
Later boot stages can just read the CBMEM ID to retrieve the ISH
version if required.
Finally, ensure this feature is platform specific hence, getting
enabled for the platform that would like to store the ISH version into
the CBMEM and parse to perform some additional work.
