Just wondering: if the carrier board can easily work with different
SoMs.. in which case, we could do overlay to create the som + carrier
overlay to create rdk dtb - this might allow the scheme to scale to
additional SoMs and carrier combinations.. and the SoM dtb could be
sufficient for something like a bootloader.
