Bootloaders may also need to write to NAND. So, they need to share the
same bad block information with the kernel. Currently, I am not aware of
a bootloader for mxs which support BBT without OOB. Unless this has
changed meanwhile, we shouldn't make this default, because they can't
share the same information then. To be on the safe side regardings
regressions, we shouldn't make this default as well, come to think of
it.
