I think Hygon wanted to superficially show it is not really an AMD. For
example, the Hygon thing doesn't do SME/SEV. AFAIK.
So we can just as well check only family but I'd say the vendor thing is
laying the grounds for the future where reportedly it will differ more
from an AMD. And then we can start splitting code more based on vendor
and not look at family at all.
But for right now I think we should strive to keep the changes as small
as possible and only do real splitting when they start adding new
functionality. Which would mean having a hygon_edac.c too, for example.
All, IMHO, of course. Sharing code between vendors is always yucky.
