Subject: memory: assign MemoryRegionOps to all regions
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2cdfcf272d1a38e22879aecae83e95be51369b2d;p=qemu.git

memory: assign MemoryRegionOps to all regions

This allows to remove the checks on section->readonly.  Simply,
write accesses to ROM will not be considered "direct" and will
go through mr->ops without any special intervention.
