[Qemu-devel] [PATCH] hw: misc: Add Aspeed XDMA device

2019-06-03 Thread Eddie James
The XDMA engine embedded in the Aspeed SOCs performs PCI DMA operations between the SOC (acting as a BMC) and a host processor in a server. The XDMA engine exists on the AST2400, AST2500, and AST2600 SOCs, so enable it for all of those. Signed-off-by: Eddie James --- hw/arm/aspeed_soc.c
