ARM has stated that if you have the same physical memory mapped with two different sets of attribute bits you get undefined behavior.
I didn't know this is undefined behavior. But we at the Rockbox project do this on several targets without problems (cached and uncached, for e.g. simplified DMA-related code).
Best regards.
