Hi,
Attached patch implements DMA support to RC4030 chipset and simplifies
jazz IO part (at 0xf0000000), where registers contain 16 bit values.
The patch also wires DMA transfers for the SCSI adapter in the Jazz
emulation (Mips Magnum 4000 and Acer Pica 61).
Changes since v1:
- Support reuse of esp callback functions up to DMA engine
- Don't keep in memory the DMA table, but read it when needed
Changes since v2:
- Don't use cpu_single_env in the DMA transfer function, as it is NULL
in the aio path
- Multiple improvements to the DMA transfer function: report errors to
the caller, support for non contiguous physical pages...
