11 involving the host CPU. Currently, this framework can be
12 used to offload memory copies in the network stack and
13 RAID operations in the MD driver. This menu only presents
14 DMA Device drivers supported by the configured arch, it may

623 Support for the NVIDIA Tegra20 APB DMA controller driver. The
624 DMA controller is having multiple DMA channel which can be
625 configured for different peripherals like audio, UART, SPI,
626 I2C etc which is in APB bus.
627 This DMA controller transfers data from memory to peripheral fifo
628 or vice versa. It does not support memory to memory data transfer.

692 channels, Memory Mapped to Stream (MM2S) and Stream to
693 Memory Mapped (S2MM) for the data transfers.
694 AXI CDMA engine provides high-bandwidth direct memory access
