What's the problem with doing it for a single target? That's
what I did for versatilepb. I think any CPU that doesn't have
inb/outb type instructions (x86 does, and I think also alpha
but I forget) should not be using address_space_io; but the
easiest way to get there is to convert the PCI bridges one at
a time as we have maintenance effort to do so.
