The DMA controller driver only knows how to do memory to memory copies, and
the AAU driver how to zero a chunk of memory.
Use them to process big (>=1KB) copying/zeroing.
work out of the box too, but I have no hardware to test.
It works well enough to go multiuser. Network works, SATA does not, as I have
no drive to test.
Thanks to Intel for sending such a board.
