Thanks for the pointer! Yes, it seems like that might be similar to what I
need... create new address spaces (rather than using the "system" address
space) for the PCI memory and I/O regions (I need to do this for PCI
configuration space, too, FWIW...), then in my sparse ops handlers, decode the
bus address and size, and then call address_space_{read,write}(). Have I got
the gist of it?
