Hrm... it's per processor, not per board. I didn't feel like

digging

which board uses which processor and go fixup all the ppc_md's

Sounds like something a generic function could probe for from the

DTS.

I'll look at doing something here when I start making 44x
multiplatform
(soon).

Well... we already probe the CPU type.... from cputable.

So if there was a place to put that, it would be the cputable.

It could make sense to have _both_ platform (ppc_md) and cputable
functions, since some info is likely to be core-specific, other might
be board/chipset/SoC-specific.

Yup. I need to look into it. We would call ppc_md. first and define
3 result codes: one for faulting, one for returning (fixed up) and one
for passing along (to the per-cpu code).

In fact, in theory we would need to also handle L1 parity errors on 970
now that I think of it...
