AFAICS you're not losing any output from after serial init. Things look
as I expect them to look. stage0 has no output and stage1 is rather
silent (except the banner, which is indeed printed). The stuff before
the banner comes from a not-yet-setup serial port.
I said in the past that we shouldn't send stuff to serial before serial
is set up, but my pleas have been ignored largely due to the fact that
some hardware has working serial by default, so the problems were not
seen in practice.

And yes, this is easy to fix. Keep a global variable (working_serial)
and check it before sending stuff to the serial port. Set that variable
directly after serial console init.
