ide: Add tx4939ide driver (v6) (37897989) · Commits · 戴 / test

This is the driver for the Toshiba TX4939 SoC ATA controller. This controller has standard ATA taskfile registers and DMA command/status registers, but the register layout is swapped on big endian. There are some other endian issue and some special registers which requires many custom dma_ops/tp_ops routines and build_dmatable. Signed-off-by:
