Intel Meteor Lake QS silicon provides better size optimized pre-x86
reset blobs.
This patch creates a new flash layout (FMD) for QS to accommodate those
optimizations, and renames the existing FMD for ES (pre-prod) silicon.
Comparative analysis between QS and ES flash layout is here:
For QS silicon:
- SI_ALL reduced from 9MB to 8MB.
- SI_BIOS increased by 1MB (from 23MB to 24MB) to fill in the 32MB SPI
layout.
- ME_RW_A/B reduce from ~4.5MB to 4MB.
- Ensure RW-B slot is starting at 16MB boundary.
- Unused space increased by 1MB.
For ES silicon:
- SI_ALL: 9MB
- SI_BIOS: 23MB
- ME_RWA/B: 4.5MB (for ISH) and 4.4MB (non-ISH).
- Unused space 3MB (for release) and 2MB (for debug) layout.

This patch eliminates the need to maintain separate FMD files for rex
variants and rex variants with ISH. It does this by using the
BOARD_GOOGLE_MODEL_REX_EC_ISH config to differentiate between ME-RW
layout sizes.
TEST=Able to build and boot google/rex and google/rex_ec_ish.

This patch updates the Rex debug flash layout to optimize WP_RO to 4MB.
Changes for chromeos.fmd:
SI_BIOS:
RW_SECTION_A/B: Increase to 7.5MB.
RW_LEGACY: Introduce with 1MB.
RW_MISC: Increased to 1MB.
RW_UNUSED: 2MB (reserved)
WP_RO: Reduce to 4MB
Additionally, ensure RW_SECTION_B region starts at 16MB boundary in the
SPI Flash.
BUG=b:277143384
TEST=Able to build and boot google/rex with FSP release and debug image.

This patch updates the Rex flash layout to allow CSE Lite FW
update and accommodate multiple ESx SoC stepping blobs.
For default chromeos.fmd
SI_BIOS:
RW_SECTION_A/B: Increased by ~1.9MB.
RW_LEGACY: Reduce to 1MB.
RW_MISC: Reduce to 152KB.
- Drop RW_SPD_CACHE
- Optimize other sections
Additionally, moved RW_LEGACY under extended BIOS region.
For chromeos-debug-fsp.fmd
SI_BIOS:
RW_SECTION_A/B: Increased by ~1.2MB.
RW_LEGACY: Dropped
RW_MISC: Reduce to 152KB.
- Drop RW_SPD_CACHE
- Optimize other sections
BUG=b:262868089
TEST=Able to enable CSE update on google/rex and have free space
to add one more PUNIT FW for support different SoC stepping.

Debug FSP is ~920KiB larger than release FSP and we don't have
sufficient space for rex flash layout.
Remove RW_LEGACY and split them into RW_SECTION_A/B so we can have a
room for it.
Note: This fmd will only used for internal testing/debugging and not for
the firmware in released devices.
BUG=b:262868089
TEST=Build google/rex with CONFIG_BUILDING_WITH_DEBUG_FSP.
