So requiring that a bootloader can update the DT _independently_ of
everything else is a bit much for some devices.

In my opinion, this use case you're illustrating above simply could
continue to _not_ use DT at all. =A0If your NOR flash is so small that yo=

cannot spare some extra erase blocks, then this is a deeply embedded
profile the current DT-on-ARM push is not really meant for. =A0You would
be much better with a minimally configured kernel with all the hardware
info statically compiled into the kernel and get away without all the DT
parsing code altogether, like you're already doing today.

While I think DT for ARM has advantages, I don't see us dropping the
legacy ARM methods anytime soon, especially for existing or extremely
constrained targets.

I completely agree.
