Linux kernel.

sorry, can't accept - this breaks r1.1 based boards:

Oops. Thanks a lot for testing.

I think I know why it breaks, we should use RGMII_ID for < 2.1
revs (at least that's what we have in Linux by default). I don't
have r1.1 CPUs, can you please try this patch on top of the
current patch set?

If it'll work, I'll repost a fixed version of this patch.

that worked, thanks.

I fixed up the original commit; I'll push shortly.

Ben, I'm picking up 1-2/5 (unless you have already; I'm behind on the
list) - hope you don't mind.
