Subject: hw/microblaze: Restrict MemoryRegionOps are implemented as 32-bit
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6909b616efbc9b627a0c9ea87d25a10d508cc879;p=qemu.git

hw/microblaze: Restrict MemoryRegionOps are implemented as 32-bit

All these MemoryRegionOps read() and write() handlers are
implemented expecting 32-bit accesses. Clarify that setting
.impl.min/max_access_size fields.
