Either in addition to or instead of. The specific id hex can let you determine more specifically which cpu
each dir table is for.
Or, barring that. Its my understanding that you're using the high bytes to determine generation, but we do know
many full IDs from the coreboot project, so something like Zen 3 (Cezanne) for the bytes 0xBC0C0140 could be useful.
Or perhaps both. 0xBC0C0140 Zen 3 (Cezanne) would be most informative.
