Two things.  First, should I or should I not need to have
CONFIG_CONSOLE_MUX set?  If I set it, adding serial=eserial3 to my
default environment switches from eserial0 to eserial3 when we get to
that point in the boot, otherwise I do have to manually setenv serial
eserial3 for anything to happen.  And the second thing, I can't get any
output on the other UART, either way.  It goes away from eserial0 but
nothing ever shows up to eserial3 (the easiest one here to test).
