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. 14 15config DMA_CHANNELS 16 bool "Enable DMA channels support" 17 depends on DMA 18 help 19 Enable channels support for DMA.
