I need some help to understand Ide driver code on Linux 2.6. I have to
actually port it System On Chip (SOC) ide controller. Could be a
document, some write-up, weblink or general comment.
I gone through the code, found that initializing port[1f0-1f7] and
dma-base is critical. But am not quite sure.

Appreciate any help as it is urgent.
thanks,
