New in this version:
MemoryRegionOps gained .old_mmio and .old_portio members, which allow
reusing old-style callbacks with the new API. All uses were converted,
except for eepro100.c, which uses the same MemoryRegionOps for both
portio and mmio. Some intermediate patches do introduce dispatching
callbacks, but they are removed later.
Caveats:
- some devices still grab a global memory region instead of inheriting
it from their bus. Seen in the code as #include "exec-memory.h"
Could you write up a quick document on how to use this new api for docs/?
There's bits I don't like about the interface but I think it's a huge
improvement over what we have now so I'm inclined to commit once it
includes documentation.
