Platform/Intel/KabylakeOpenBoardPkg/KabylakeRvp3/BiosInfo/BiosInfo.c and Platform/Intel/KabylakeOpenBoardPkg/GalagoPro3/BiosInfo/BiosInfo.c are identical files. Can we move this up to the parent KabylakeOpenBoardPkg and use one PEIM for both platforms?

For now, this is definitely possible.
It may also be viable long term. The table is closely tied to the FV layout which is
standardized under Minimum Platform. Firmware volumes that may come and go like those for
a particular advanced feature would end up as child FVs under a FvAdvanced parent that
would be covered in the BIOS Info table. It seems that the FVs that will eventually be described in
the table will remain fixed while their contents are customized by individual boards.
Also due to the FV standardization, the FVs that compose the IBB segment definition in the table
for S-ACM verification/measurement can likely be consistent across the boards in addition to the
post-IBB FVs which leads to a standardized IBB/OBB definition. Some boards within a package may
have Boot Guard enabled while others don't but having the FVs identified as IBB, post-IBB, or
exclude from FIT in the table will not negatively impact the Boot Guard disabled case.
I agree we should start with KabylakeOpenBoardPkg having a single copy of the PEIM used for
all boards.
Thanks,
Michael

BiosInfo.c:
BiosInfoEntryPoint () function description should be updated. The function installs the BiosInfo PPI
but also produces the BiosInfo HOB.
It also looks like you can remove the following macros:
#define INDEXPORT_TO_ADDRESS(x) (x)
#define DATAPORT_TO_ADDRESS(x) ((x) << 16)
#define PORTWIDTH_TO_ADDRESS(x) ((x) << 32)
#define PORTBITNUMBER_TO_ADDRESS(x) ((x) << 40)
#define PORTINDEXNUMBER_TO_ADDRESS(x) ((x) << 48)
