I don't even understand why you want to create a generic pci_address_to_pio implementation, when we don't need that for arm64 at all. Unless I'm missing something important, that function is only called in case of PCI_PROBE_DEVTREE with pci_of_scan on PowerPC. I don't expect any architecture to do the same thing, and the only other architecture that needs something like it (sparc) has a different implementation.
Because in my [v7 2/6]* patch for the generic host bridge support I start using pci_address_to_pio to fix the conversion of PCI ranges to resources. That requires an arm64 (or more correctly, an arch with memory mapped IO specific) version of pci_address_to_pio().
Yes, but why do you use it there?
