If one does
$ git grep -n "\<\(CONFIG_\)\?SERIAL_CONSOLE\>" | grep -v defconfig

one gets a few hits (summarized):
- arch/m68k/Kconfig.devices: discussed here;
- arch/sparc/Kconfig: apparently unused, and can be dropped;
- arch/xtensa/Kconfig and arch/xtensa/platforms/iss/console.c: the only
other current usage (note that the "S6105" platform, mentioned in the
Kconfig file, seems not to use it);
- drivers/staging/serial/68360serial.c: uses CONFIG_SERIAL_CONSOLE, but
I don't see how it can actually be set for that driver;
- drivers/tty/amiserial.c: discussed here.

I see nothing universal about it: two independent usages, one in
*/iss/console.c and one in */amiserial.c. So I'd say these can be
renamed to (say) ISS_SERIAL_CONSOLE and AMIGA_BUILTIN_SERIAL_CONSOLE.
