The reason I chose this representation is because it allows us to more easily search for the guids in the AGESA FSP source.

If the coreboot GUID_INIT function used a uint64_t for the last segment instead of 8 uint8_t values, I'd support it. That would match the standard GUID representation instead of doing our own thing.
