Consider a board model which puts together some RAM and
devices. It ought to have the same interface for passing this
up to the CPU whether it's doing so directly or via some SoC
container device. For the SoC container case, this has to be
by passing a MemoryRegion, since the SoC will want to add
some devices of its own to that region. So the interface for
passing things to the CPU should also be a MemoryRegion
(which the CPU then turns into an AddressSpace for its own
internal use.)

I haven't look closely at those final patches either, but I think I agree with Peter.

It's certainly okay if Andreas picks up these patches, since there's no formal MAINTAINER for the memory API.

However, I'd prefer to first apply the patch to fix exec.c in order to keep bisection as clean as possible.

Thanks!

Paolo
