As part of boot time optimization, one of the culprit was CSE where
response to End Of Post (EOP) command used to take ~60ms. Earlier patch
was pushed to delay the EOP to reduce response time to ~5-7 ms. During
this stage overall platform boot time was ~1.15 seconds.
Once boot time was optimized to ~ 1 seconds, CSE EOP time again
increased to ~80 ms since coreboot used to send EOP at the time where
CSE was busy. This created some back and forth moving of sending EOP
command function within coreboot sequence.
Upon debugging using traces, it was found that coreboot used to send
EOP late where CSE was busy loading other IP payload, so it might take
more time to respond.
In order to avoid delayed response, coreboot has to send EOP in
stage when CSE is done with firmware init and it will be ready to
serve EOP as soon as possible. This also aligns with previous flow where
FSP used to send EOP once silicon init is done and coreboot used to
rely on FSP to send this message.
Moving EOP to earlier stage (From SoC) meets the requirement and CSE EOP time
reduces from ~60 ms to ~20 ms on Brya board.
Note that once SoC code sends EOP, coreboot common code won't send it
again since common code already has check in case EOP is sent earlier.

Earlier while trying to optimize boot time End Of Post (EOP) time kept
increasing (~80 ms) when boot time decreased to around 1 second.
This was because CSE was busy with own firmware loading.
When EOP was moved later in boot stage it again created issue since CSE
got busy with other payload loading for OS boot, so response to EOP
got delayed by ~70-80 ms.
In order to avoid delayed response, coreboot has to send EOP in
stage when CSE is done with firmware init and it will be ready to
serve EOP as soon as possible. This also aligns with previous flow
where FSP used to send EOP once silicon init is done and coreboot used
to rely on FSP to send this message.
Moving EOP to BS_DEV_INIT boot state meets this requirement and CSE EOP
time reduces from ~60 ms to ~20 ms on Brya QS board.
Since this setting might vary for each SoC, SoCs can decide when to send
EOP in the boot sequence. This patch adds Kconfig option to send EOP via
SoC

This change will allow the SMI handler to write to the cbmem console
buffer. Normally SMIs can only be debugged using some kind of serial
port (UART). By storing the SMI logs into cbmem we can debug SMIs using
`cbmem -1`. Now that these logs are available to the OS we could also
verify there were no errors in the SMI handler.
Since SMM can write to all of DRAM, we can't trust any pointers
provided by cbmem after the OS has booted. For this reason we store the
cbmem console pointer as part of the SMM runtime parameters. The cbmem
console is implemented as a circular buffer so it will never write
outside of this area.

Nissa boards are curretly using chromeos.fmd file of brya. The SPI flash
layout for brya is of 32MB size, and nissa is expected to have 16MB SPI
NOR flash. The current composition of AP firmware exceeds 16MB. To get
an estimate of the unutilized region in the current flash layout for

size to under 16MB and to remove the RW_UNUSED regions from the final

Add SOC_INTEL_CSE_LITE_COMPRESS_ME_RW Kconfig to enable compression on
ME_RW blobs. Select the Kconfig to add LZMA compressed ME_RW blobs to
ME_RW_A/B regions.
On ADL-N, this results in savings of ~665KB in each of ME_RW_A/B
regions.

With LinuxBoot Linux relied on the legacy method of fetching the RSDP
pointer to get ACPI. This uses a more modern approach available since
2018 on the Linux kernel, which involves filling in the zero page.
This method takes precedence over any other method of fetching the
RSDP in Linux (UEFI, Kexec, Legacy/BIOS). Some UEFI zealots are
threatening that legacy code will be removed from Linux so it's best
to already adapt to that possibility.
Tested on Qemu:
- With qemu the RSDP is always in the EBDA, so checking if Linux uses
the provided pointer is better done with a forced bad entry
- With a fake bad pointer Linux correctly does not find RDSP

The ACPI RSDP can only be found in:
- legacy BIOS region
- via UEFI service
On some systems like ARM that legacy BIOS region is not an option, so
to avoid needing UEFI it makes sense to expose the RSDP via a coreboot
table entry.
This also adds the respective unit test.

If it is not cleared and the number of strings is fewer than last
iteration, the match[3] will keep the last value, which actually
should be empty.
Add assert to make sure the level is a legal value.
