Awesome! I'm happy to see barebox support for one of the more popular
Linux ARM architectures.

The patches look quite good and there's not much to be done to
make them ready for merging.

I'm just on the way to merge the Linux devicetree files into barebox
and use them where possible so we do not duplicate the devicetrees in
barebox. Could you post a followup once to base the rockchip dts files
on the Linux dts files once I have everything in place? I saw that you
already use the mainline dts files, but these do not contain the
ethernet nodes for example.

Also I'd like to let rockchip use the multi image mechanism. This is not
much work when you know what to do. You could change it yourself or I do
the change for you, but in this case, could you give the result a test?
