We need to find some other way to solve this or move all of the
partition stuff to Kconfig as well so we can default some stuff on and
then turn it off in cases.

Can you really have console on the other locations?  On the AM335x EVM,
it was possible, and doubly so with people making RS232 capes for
Beaglebones.  That's why it's exposed there.

No more commands in board directories, and we should be able to do this
generically.  In fact, we should already be able to make fail to boot
Linux fatal which I gather is what this is used for.
