| 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. | |

| 19 | Enable channels support for DMA. Some DMA controllers have multiple | |
| 20 | channels which can either transfer data to/from different devices. | |

| 26 | Enable support for a test DMA uclass implementation. It stimulates | |
| 27 | DMA transfer by simple copying data between channels. | |
