Not a bad idea, since most DMA controllers are learning and becoming
descriptor based. Please consider that DMA controllers, the devices
to which they are connected, and the integration is going to be unique
to the parts, boards and devices. Forcing this to be too generic will
likely fail, make a mess of the software, and not benefit anyone.
Have fun!
