Both the Kconfig and DM transition mean that we'll probably end up with
some ugly bits for a while.  But I want to take a poke around again and
see if it can be a bit better now, today.

No, checkout say configs/A10-OLinuXino-Lime_defconfig and see all of the
DM_* stuff that's in there.  Hans' point is that it shouldn't be since
they must be set.  Having them correct in the config files (IMHO) helps,
but Hans' point I believe (And I see the validity there, there's _60_
sunxi boards today and more every week practically) is that making each
new board set this is wrong on many levels.
