mb/google/rex: Add new FMD for prod (QS) Meteor Lake silicon
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.
