AFAIK the aliases numbering is supposed to match the board or case labels.

Those pesky FORTRAN programmers, counting from 1 ;-)

On Koelsch (and Salvator-X(S)), they are called "debug0" and "debug1".

These used to be /dev/ttySC6 and /dev/ttySC7, but got renamed in
commit 1f75cdac773bc9c9 ("ARM: shmobile: koelsch: Rename SCIF[01] serial
ports to ttySC[01]").

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
