Allow overlays to be applied to any DTB. This adds around ~40% to the
total size of the DTB files on average.  
Is this unconditionally enabled or can it be turned off by some CONFIG? We have
our own defconfig so I would not worry if if is enabled in omap2plus_defconfig
and disabled in ours.

We have several devices where the boot loader can't handle overlays (never touch
a working boot-loader :) So this seems to only contribute to build and load time
without benefit.
As long as you do not add overlays, the bootloader does not care. I would
like to simply carry around the 1-bit mmc overlay for one broken board.
That would help me. So I think there is a benefit but nobody forces
you to use it.
Well, it does not force to use the really good feature, but it forces to add
~40% more file size and some more compile time, if I understand it correctly.

This makes me think that it should be an option to turn it off completely (and
not just ignore it by the boot loader).

Nikolaus
