I trust that AMD is not going to hunt us down if we check out the complete svn tree (copy) with the intent to develop for non-AMD systems. Still, the legalese feels a bit weird.
You bring this up every time I update microcode patches. This has been worked out in the past. The statement seems very straight forward to me (but I am not a lawyer).

AFAICS it could happen that different "Equivalent Processor IDs" have the same patch level. Naming the microcode files only after the patch level would cause all sorts of interesting conflicts in that case. How about a naming scheme like mc_patch_$EQUIVALENTREVISION_$PATCHLEVEL.h
I don't see your point. The code already handles equivalent processor ids. I put the table in so you didn't have to read the revision guide to understand what is going on. What you suggest only makes it more difficult if different equivalent ids have the same patch level.
#include "mc_patch_01000065.h"
- /* Barcelona rev B2, B3 */
#include "mc_patch_01000083.h"This looks like manual source code editing is required to support Barcelona processors before B2. May I suggest a Kconfig variable for that?
Yes, it is manual editing so I will add a config option to v2. A Kconfig variable would be great when you port it to v3. :)
