| Enable driver model for DMA. DMA engines can do |
| asynchronous data transfers without involving the host |
| CPU. Currently, this framework can be used to offload |
| memory copies to and from devices like qspi, ethernet |
| etc Drivers provide methods to access the DMA devices |
| buses that is used to transfer data to and from memory. |
| The uclass interface is defined in include/dma.h. |
