The Pubkey(0), PSP bootloader(1) and IKEK(0x21) should be put to

long term and A/B recovery layout only. So the amdfwtool should be
changed for Sabrina.
The old levels of these 3 FWs are for Cezanne, which doesn't use AB
recovery now. Just set the specific field levels in generic Cezanne

If the table address mode is 2, the address in each entry should be

But in set_efs_table, it has case for Stoneyridge. The boards also
