I don't know if this is a typo here in amd-apcb or both are possible.

I have seen "BCBA" in a firmware image from an ASRock A520M-HVS board, version A52MIX_2.73. And it is also in Fiano (just in different notation): https://github.com/linuxboot/fiano/blob/d844cd98141518f41b3e4012bcf419984074a2b4/pkg/amd/apcb/internal.go#L16
