See the arch/arm/mach-kirkwood directory in the Linux tree.  All the
*-setup.c files declare different sets of GPIOs in static structures.
If you know a way to "easily" detect them at runtime, that could unify
a lot of this code.  I'm sure a patch would be welcome.

(Note that I didn't say what you quoted.)  But it was a brain slip; I
was just remembering a difference in the physical connectors for the
serial ports.
