linux-omap, linux-arm-list should also be CCed, Benoit needs to be addressed for allowing him to merge,
I have not done a proper schematics Vs data manual review yet (apologies on that), but, a couple of comments:

Where is the interrupt line to MPU? if it is not hooked up, why the interrupt controller?
