Sure, but I'm *explicitly* avoiding relying on DT for this, because
there are plenty of things that happen before DT can or should be
touched that might warrant serial port output.
The kernel has exactly the same kind of feature; log messages can be
sent out through an SoC-specific earlyprintk mechanism. In the U-Boot
case though, I don't plan on replacing the serial port based on
information from DT, but simply setting it up much much earlier via a
simpler mechanism.
