That's something like it - asked Andrew via IRC on Saturday:

Do we want to do the XAUI thing as one patch to avoid any breakage, and
if so via whom?

and haven't had a response.  Normally arm-soc folk want patches
touching arch/arm/boot/dts to go via their tree.

So, until I know what to do, I can't proceed with this... and I've
soo many outstanding net patches now that I'm losing track of where
each patch I've sent out is.  Sorry, I'm failing.
