Basically document number 21656 Athlon Process BIOS Software & debug
developers guide.  Has all of that except my chapter 4 on processor
caches, that basically says nothing.  I get the impression that for
the slot Athlons you need to do something but for the socket
processors you really don't.  There is a changlog entry that says they
removed much of the discussion on L2 init. 

So I feel like I should have what I need but it isn't there.

If it wasn't for your earlier comment about not having L2 cache init
I would assume the socket athlons were like the socket athlons and
nothing actually needs to be done.
