| 7 | Enable driver model for DMA. DMA engines can do |
| 8 | asynchronous data transfers without involving the host |
| 9 | CPU. Currently, this framework can be used to offload |
| 10 | memory copies to and from devices like qspi, ethernet |
| 11 | etc Drivers provide methods to access the DMA devices |
| 12 | buses that is used to transfer data to and from memory. |
| 13 | The uclass interface is defined in include/dma.h. |
