Yes, I'm hoping to add the dtb editing support sometime over the next
few weeks.  That way, we can use Willy's atags patch in there, and the
kernel never knows the difference.

It isn't high on my priority list atm, so if someone else is motivated,
I've been borrowing code from barebox to flesh out impedance-matcher.
Patches are welcomed ;-)

thx,

Jason.
