Subject: DMA controllers (about IOAT vs. BestComm)

Quickie question, has anyone from the PPC team looked at the work Intel have
done on the generic DMA engine interface and their IOAT driver?

How does it fare for the possibility of adding common PPC DMA controllers
(52xx BestComm, PowerQUICC II/III, MV63xx, Tsi10x..) for the very basic
memcpy style offloads, not to mention the networking stack, any XOR
engines present and so on?

Or did they make it a little too x86-specific?
