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

This change ensures mutually exclusive options, avoiding unnecessary

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.)

Also make those includes available to tests so that their functions can

unconditionally, but this should be fine since the tests are standalone

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.

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

And _data & _edata is also useful to clean up the sensitive data on the

When cleaning the sensitive data in the memory, we will want to prevent
zero out the content of tbb_buffer. Move the ttb_buffer to a standalone

Some sensitive data may remain DMA buffer, we will want to zero out
everything on the DMA buffer before we jump into the kernel to
prevent leaking sensitive data into the kernel.
To accomplish that, we will need this function to get the range of
memory that can be allocated by the dma allocator.

The value from raw_read_cntfrq_el0() could be large enough to cause
overflow when multiplied by USECS_PER_SEC. To prevent this, both
USECS_PER_SEC and hz can be reduced by dividing them by their GCD.
This patch also modifies the return type of `timer_hz()` from
`uint64_t` to `uint32_t`, assuming that in practice the timestamp
counter should never be that fast.

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.

Patch adds:
- vboot_fail_and_reboot() for vboot failures handling.
- reboot() weak implementation for payloads to implement, used
by vboot_fail_and_reboot().
- vboot_recovery_mode_enabled() to check if recovery mode flag is set in
vboot context. Implemented for future libcbfs implementation
of VBOOT_CBFS_INTEGRATION in libpayload.

To fully and easily implement fallback/recovery in libcbfs with vboot
support the codebase requires access to vboot context. Moving context
management to libpayload allows to avoid unnecessary overhead and code
complication and still allows payloads to access it in a way it was
designed. Access to this codebase will also allow implementation of e.g.
vboot_fail_and_reboot() and other helpful utilities used by coreboot and
depthcharge.
