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. -- MST
