The names and numbers are already extremely confusing in the code we have.
Maybe we can use the addition of the new code as an excuse to clean up
what we have ;-)

I agree that "armada" is a rather bad choice, because chips under that name
include both the pxa/mmp family and the orion/kirkwood/mv78xx0/dove family
which AFAICT don't have much in common at all besides the CPU cores.

One option would be to move all DT-enabled board files under plat-orion
once they are fully done, and leave just the non-DT board files in the
individual directories until they have all been converted. We can start
with the platform code that's being discussed here and move over the
kirkwood and orion5x board-dt.c files once they don't depend on anything
else in those directories any more.
