Change in coreboot[master]: WIP: Use SPDs from PSP BIOS table type 0x69 based on GPIO straps
by Nikolai Vyssotski (Code Review) 25 Oct '22

Nikolai Vyssotski has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/45278 ) Change subject: WIP: Use SPDs from PSP BIOS table type 0x69 based on GPIO straps ...................................................................... WIP: Use SPDs from PSP BIOS table type 0x69 based on GPIO straps Use GPIOs mapping defined in APCB GET_SPD_FROM_GPIO to fetch correct SPD block from PSP BIOS table entry type 0x69 (BIOS_SPD_DATA). There is only one APCB now with no SPD data in it. No need for board ID getting method. This will save ROM space consumed by multiple APCB copies in the past. This is a working example of an implementation tested on Dalboz. It does not require patching with APCB_EDIT_TOOL. All SPDs are assembled in one type 0x69 blob and inserted into PSP BIOS directory.
