Hi,
rc4030 chipset contains the DMA controller. Some devices (like the Jazz
netcard[1]) need to access the DMA memory without using a DMA channel.
The chosen prototype "void (*memory_rw)(void *opaque, target_phys_addr_t
addr, uint8_t *buf, int len, int is_write);" is quite similar to
cpu_physical_memory_rw().
Document also some registers and remove one hack.
I also put all returned functions/pointers by the rc4030 init function
to a structure to not add two new output parameters to the init function.
Signed-off-by: Hervé Poussineau <address@hidden>
Changes have been tested on Linux, NetBSD, and Windows NT/MIPS.
