I normally ask people to put the aliases into the board specific dts file,
to account for machines that do not have all the uarts, or that number them
differently from the SoC.
I didn't know about U-Boot setting the stdout-path property, but that's
great, as long as U-Boot uses the same numbering of the uarts that the
board uses. Do you know if that is normally the case?
