It is not pointless. ?Never it was in the cards to convert old platforms

New stuff doesn't necessarily mean new boot loaders. ?I don't have a lot
of control over the bootloaders on MSM. ?We can probably move away from
ATAGS, but only after every kernel that could possibly boot on that

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.
