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.
