to look at the new patch set (#4).

soc/amd/cezanne: Add an option to enable A/B recovery scheme
Extracted from NDA spec #56995: "The A/B recovery scheme formally separates the SPI flash space into different partitions; a primary, “A” and secondary, “B”, which hold the same set of system firmware. Under this scheme, the partitions A and B can hold identical contents initially, but each partition can be updated individually.
Normally the system boots from partition A, but if the A partition is found to be corrupted, the system will switch to partition B and boot. The OEM BIOS can then choose to continue the boot from partition B, or repair partition A using contents from partition B."
The Cezanne platform supports both A/B recovery and no recovery method. It needs this flag passed to amdfwtool to disable the A/B recovery layout.
