Hi all:

This patchset introduces you to the 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.
