      8	  Enable support for the AMD PTDMA controller. This controller
      9	  provides DMA capabilities to perform high bandwidth memory to
     10	  memory and IO copy operations. It performs DMA transfer through
     11	  queue-based descriptor management. This DMA controller is intended
     12	  to be used with AMD Non-Transparent Bridge devices and not for
     13	  general purpose peripheral DMA.
