mb/google/mtlrvp: Update MTLRVP Flash Layout
This patch updates the MTLRVP flash layout to allow CSE Lite FW
update and accommodate multiple ESx SoC stepping blobs.
SI_BIOS:
SI_EC: Removed
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:271407315
TEST=Able to enable CSE update on MTLRVP and have free space
to add one more PUNIT FW to support different SoC stepping.
