The VIA CPU support code has been a bit neglected. With the upcoming support for more C7 based systems, I changed the code to have a seperate model_c3 and model_c7, as we have with all other cpu types.
model_c3 was simplified to catch all c3 cpus, not only the hand maintained.
model_c7 supports correct frequency stepping for many C7 cpus.
Best wishes Stefan

- split model_centaur into model_c3 and model_c7
- simplify and improve cpuid table
- add speedstep support for VIA C7 based CPUs

Is the patch tested on hardware, ideally some C3 and C7 and epia/epia-m system? It should not break any boards, of course. Is it abuild-tested, too? I didn't check if it compiles...
Patch looks good otherwise, with the above changes I'll ack (I cannot test on hardware, though).
Uwe.
