Hello, is there anybody out there?
There's nice and simple patch enabling device tree on n900, it is even
reviewed by Aaro, and it is neither applied nor are negative comments
coming? ...for a month...?
Tony also seen the patch and comment was "Benoit takes these", so I
assume it looks basically ok.
Benoit, you are supposed to maintain device tree for omap2.
[I wonder if this is clean-enough cause for "trivial in resubmit
mode?]

This adds device tree with neccessary support to boot with functional
video (on both emulator and real N900 device).
