PS12, Line 332: Bootblock
> Hrmm, does verstage not verify bootblock?

Actually not since amdfw.rom (in RO/Coreboot) contains metadata hash anchor and hence is excluded from CBFS verification. Also bootblock is not signed against AMD chain of trust and hence is not verified by PSP. So it makes sense to verify the bootblock by GSC.
