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. Some DMA controllers have multiple 20 channels which can either transfer data to/from different devices. 21 22config SANDBOX_DMA 23 bool "Enable the sandbox DMA test driver" 24 depends on DMA && DMA_CHANNELS && SANDBOX 25 help 26 Enable support for a test DMA uclass implementation. It stimulates 27 DMA transfer by simple copying data between channels. 28 29config BCM6348_IUDMA 30 bool "BCM6348 IUDMA driver" 31 depends on ARCH_BMIPS 32 select DMA_CHANNELS 33 help 34 Enable the BCM6348 IUDMA driver. 35 This driver support data transfer from devices to 36 memory and from memory to devices. 37 38config TI_EDMA3 39 bool "TI EDMA3 driver" 40 help 41 Enable the TI EDMA3 driver for DRA7xx and AM43xx evms. 42 This driver support data transfer between memory 43 regions. 44 45config APBH_DMA 46 bool "Support APBH DMA" 47 depends on MX23 || MX28 || MX6 || MX7 48 help 49 Enable APBH DMA driver. 50 51if APBH_DMA 52config APBH_DMA_BURST 53 bool "Enable DMA BURST" 54 55config APBH_DMA_BURST8 56 bool "Enable DMA BURST8" 57 58endif 59 60if ASPEED_SPI 61config ASPEED_SPI_DMA 62 bool "Enable Aseepd SPI DMA" 63 default y 64endif 65 66endmenu # menu "DMA Support" 67
