That driver depends on MV64X60 and I don't see anything in the tree
enabling it and I can't select it AFAICT:

config MV64X60
        bool
        select PPC_INDIRECT_PCI
        select CHECK_CACHE_COHERENCY

PPC folks, what do we do here?

If not used anymore, I'd love to have one less EDAC driver.

Thx.
