[Qemu-devel] [PULL 12/15] doc/memory.txt: correct description of MemoryRegionOps fields |

From: Peter Maydell <address@hidden>
Probably what happened was that when the API was being designed it
started off with an 'aligned' field, and then later the field name
and semantics were changed but the docs weren't updated to match.
Similarly, cpu_register_io_memory() does not exist anymore, so
clarify the documentation for .old_mmio.
