Help text

Enable support for the AMD AE4DMA 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.
