Yes, as I said before, I want to separate the "special" DT spec nodes
(aliases, chosen, reserved-memory, ... that are defined in the
chapter 3 of the DT spec) from the other, device nodes.
I see them on the top on many other boards and I believe this separation
makes sense since those are not really devices but "more extended"
properties of the board as a whole.
If you still believe those must be mixed together and sorted, please
explicitly let me know that and I will change the order.
Also, if there is any documentation that already enforces the order,
making clear that my opinion is wrong, I would appreciate you pointing
me to that.

Nikita
