Well, the current upstream code has the dma ops support. Becky is
massaging that more for swiotlb support which has been submitted to the
linuxppc-dev list. We haven't yet added runtime support rather than
compile time for non-cache coherent platforms, but it's becoming
reasonably easy to add now (though still needs to be done).

Cheers,
