I've been struggling with the following problem: bridges have two memory
ranges: prefetcheable and non-prefetcheable.
Memory in the device can be behind the prefetcheable and
non-prefetcheable memory range, but things only work correctly if
non-prefetcheable memory on the device is put behind a non-prefetcheable
range. Prefetcheable memory can go anywhere I think.
This didn't work correctly before the memory API change,
but it was easy to fix ... Now I'm not sure how.
