Subject: [PATCH] memory: Correctly return alias region type
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since memory region aliases are neither rom nor ram, they are
described as i/o, which is often incorrect. Return instead the
type of the original region we are aliasing.
