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?
Yep. That bitband device is a good example. r~
