Use stdout-path for the console. Really, the bootargs should be blank
and populated by the bootloader especially debug options.
Agree but in case of devboards we quite often disable bootloader and
load Linux image in memory via JTAG. So in that case bootargs make perfect sense IMH
FWIW, I tried this 2 years ago (v4.1 ish) per pestering by Arnd but at the time I
had to add some hacks in early 8250 driver to get this working for ARC.

We can certainly revisit this now.
