Subject: XDMA engine for AST2400


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!

Best Regards!
