What about systems using an older dts, such as one kexec:ing from an
older kernel?

Just because the device tree source is distributed in the kernel tree
doesn't mean it can give up backwards compatibility.

Like what?  Kexec doesn't work on 4xx yet.

We checked Axon, which is the only non-DTS machine that uses EMAC and
it will work fine with this change.

Sure, but similar restrictions would apply for customers who have a
flashed device tree that want to boot a newer kernel. Deprecating old
device tree support is something that should be done very carefully.

Ah, ok. I remember discussions about this patch before then, sounds like
it's safe. I just triggered on the dts-centric patch description.

Objections withdrawn. :)

In that case, we -know- there was no such thing as the proper support
for 4xx in powerpc isn't really there before 2.6.25 anyway. The only
other is Cell/Axon which we verified still works.

In fact, this patch should go in before the one changing the dts
files.

I need to test if it works on CAB, can't change the DT on those. I'll
let you know tomorrow.

This should be fine on CAB.  The rgmii node has:

compatible = "ibm,rgmii-axon", "ibm,rgmii"

so the match should still catch on the latter.

How about this patch? Ben, if you think this is ok then we should make sure 
that it goes in in this merge-window, since the other dts patch relies on it.

Thanks.

Jeff, any chance this can get into .25 soon?  I have another patch
queued up behind this one that requires it, and I don't see it in any
of your trees or branches.

Or, if you aren't opposed, I can take it through Paul's tree with your
Ack.
