You asked me privatly whether we should put dtc and friends into
barebox, by that time I answered it needs some more time. Maybe this
time has come now. I currently have a branch in the making to add dtc
support and also integration into barebox.
With this we are able to compile a dts(p) and link the binary into
barebox, so...

...you could provide a dtb in the binary *)
Furthermore you could probe barebox itself from the devicetree.
I'm still not sure whether we should add fullblown devicetrees into
barebox or stripped down versions with only the devices barebox needs.
I think time will tell.
Give me some hours time, I think then I can post a first version of the
patches.
Sascha
*) This of course shouldn't mean it can't be overwritten with another
dtb during runtime.
