Stuck getting DTS working for a new kirkwood board

Your timing is fortuitous.  :)  We were just discussing this board and
the few others that haven't been converted yet.

Let's focus on converting this board file to devicetree.  which means
you'll be setting mainlineLinux to true and arcNumber to 0xffffffff.
(means booting via devicetree).

That's a good start.

It would be helpful if you could build a kernel from the git repos.
Have you done that before?

thx,
