Part of me regrets being as positive about DT as I was on LAK back
when the decision was made. But I had just come off of a PowerPC
project, and it worked pretty well there and so I figured, "why not?".
I do think that DT is a good idea, and the runtime overhead is a
manageable problem. But it's a good idea because it creates the
opportunity for post-compile-time flexibility, which CAN make some
board files go away. Not nearly as many as some of us thought they
would however, and not without effort.
A related problem is that about 80% of what goes on in most ARM board
files should be done as module_init(), not board_init(). If we were
to be more vigilant about that, then DT would have more chances to
What were we talking about, again? :-)
