Hi Phil
This time the machine can't finish the boot again and the console was

Also, I had to make some modifications to the
arch/arm/mach-orion5x/common.c to let it compile successfully:
1 Add including of mv_dma.h
2 Add macro to define TARGET_SRAM as 9 (which is defined in addr-map.c,
so I think the clean solution should be modify the addr-map.h? Anyway,
as a quick solution the source finally got compiled)

Cloudy
