I'm not entirely comfortable with using a chunk outside of what's in the
muram node, and assuming that it's for the SMC pram -- what if there's
microcode or something there?

Since udbg is only for debugging, and is marked as potentially dangerous,
how about just using the end of muram (as described in the device tree)? 
If the muram is fully allocated, it won't happen until after the real
serial console is initialized.
