I cannot test this. But we have other devices added for E3 meanwhile, so
people surely used a console to do that? Can somebody confirm this?
After that I'll send a proper patch to linux-serial list, too.

SCIF is definitely working.
HSCIF0 can be muxed to the same pins as the console (SCIF2), so you
can actually test this using remote access, after upporting the pfc part ;-)

For local users: on E3, the QSPI pins (on 2.54mm headers on Ebisu) are
not single-use, but can be muxed to HSCIF, too.

Gr{oetje,eeting}s,
