no, that isnt true at all. you can easily have a small initramfs to
handle all of your random setup. if that's too much overhead, you can
add a late initcall to your boards file that is run after the MTD
devices are probed and let that read the required information. all of
this is more than documented:
i still see these callbacks as unnecessary overhead to solve problems
that can already be done multiple ways with existing code.
