| help |
| 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. |

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

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

| Enable some legacy DMA code for lpc32xx. It provides some direct |
| functions likes lpc32xx_dma_wait_status() which can be called from |
| other code. |
