	  Enable support for the AMD Queue-based DMA subsystem. The primary
	  mechanism to transfer data using the QDMA is for the QDMA engine to
	  operate on instructions (descriptors) provided by the host operating
	  system. Using the descriptors, the QDMA can move data in either the
	  Host to Card (H2C) direction or the Card to Host (C2H) direction.
