Those two are special SOCs due to 'extra graphics bits on', and I
suppose we could collate them. That said; I'm not sure NHM_G ever
shipped, I'm looking at a wikipedia page that says both Auburndale and
Havendale got scrapped.

Both are historical, intel is no longer making that distinction and
current chips will have _X.

These two and no _SHORT should/could be collated, I think.

I suspect these two are the same.

Bit unfortunate that; we use _XEON_D for big microservers and ATOM_*_X
for small microservers. So there's room for improvement here by unifying
this.

That one lived for 4 atom generations, but afaict it's no longer alive.

These are so far one offs, not sure about the future.

Like said in the other email, that one is not actually a _SHORT at all,
but rather the uarch is 'Goldmont Plus'
