These proposed patches aim at removing the .old_portio member of
MemoryRegionOps structure, and replacing their usage by .read/.write
handlers.
Ping.
That way, faked I/O address space can be removed from architectures
which don't have it (MIPS, PowerPC...), and commits like
a178274efabcbbc5d44805b51def874e47051325 ("PPC: pseries: Remove hack
for PIO window") can be reapplied.
The first 4 patches do the cleanup and remove the old_portio handler
in MemoryRegion structure.
The last 4 patches are simplifications, now that Portio handlers
can be called from memory core without limitation.
Changes since v1:
- handling of Portio has been moved to ioport.c (instead of isa-bus.c)
This prevents creating an ISA bus on machines which don't have one
- added last 4 patches to see benefits of removing old_portio

PPC: pseries: Remove hack for PIO window
Hervé Poussineau (7):
isa: fix documentation of isa_register_portio_list
memory: handle old_portio accesses in MMIO path
ioport: register memory regions for I/O port lists
memory: remove code dealing with old_portio
ioport: reimplement cpu_in/cpu_out using address_space_rw
ppc: simplify access to PReP I/O region
isa_mmio: simplify access to system I/O region
