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 for the SCSI adapter in the Jazz emulation
(Mips Magnum 4000 and Acer Pica 61).
Please apply
Hervé

I'd move espdma_memory_read & write to rc4030.c, that way the opaque
passed to esp_init could be directly rc4030State type.
Allocating a new dma_table every time the table changes seems
wasteful, you could read the entry from memory as needed.
