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