It feels odd/wrong to use the piix4 driver for the AMD MMIO case on SB800.
Would it not have made more sense to just make that a separate driver?
It feels like now the piix4 driver has a lot of "if SB800" for the
probing code, and then a lot of "if (mmio)" at runtime.
I've pulled this, but just wanted to mention this "that looks a bit
odd". How much code is actually _shared_ in the SB800 case?
I'm not insisting on splitting this up - maybe it all makes sense. I'm
just questioning it.
