I think that is the most likely scenario. Another option would be
to provide a replacement or second-stage boot loader that actually
understands DT and that gets loaded instead of the kernel by the
first-stage boot loader.

This has been discussed in the past, but IIRC we decided against putting
that logic into the kernel. Folks on devicetree-discuss at l.o.o might remember
the details better than me.
