Having now inspected the situation with Ux500 I can second that this
goes for the Ux500 series as well.
The U8500 firstcomer in this series and probably U5500 also is
relying on a 2009-based fork of U-boot. The U-boot for these
platforms just won't be converted to do DT.
In short we also need the ATAGs-overrides-DT-nodes approach
for a clean migration path.
