Thank you very much for your help. I am a beginner for XDMA engine, yet I do not know how to use it(>.<) ...
I learn XDMA from the driver(/drivers/soc/aspeed/aspeed-xdma.c) and AST2400 datasheet.
Are there any other examples or guidances for modifying the driver for AST2400 XDMA engine?

I am learning Openbmc with a AST2400 BMC. I am learning XDMA engine. I saw there is a driver in the linux kernel(/drivers/soc/aspeed/aspeed-xdma.c) for XDMA engine. But this driver's "of_match_table" only support AST2500 and AST2600.
Does AST2400 not support XDMA engine? But in the datasheet, the AST2400 has a XDMA engine as with AST2500.
Can some one help me? Thanks!
