Change CONFIG_SYS_IDE_MAXDEVICE from 2 to 1
Kirkwood supports max 2 Why do you want this change?
Hi Gray I take back my words. I will study more and let you know my comments on this. Sorry for noise.

Hi Prafulla,
This one was a bit of a judgement call. You are absolutely correct in what you say that Kirkwood supports two, but to the best of my knowledge, no one has yet implemented a board using both busses (I am not that familiar with OpenRD, I may have to eat my words).
For the sheevaplug, guruplug & dreamplug, it is definitely the case that only one device can be attached.
