Hi all: This patchset introduces you to the Loongson LS2X apbdma controller. The Loongson LS2X APB DMA controller is available on Loongson-2K chips. It is a single-channel, configurable DMA controller IP core based on the AXI bus, whose main function is to integrate DMA functionality on a chip dedicated to carrying data between memory and peripherals in APB bus (e.g. nand). Thanks.
