Well saying that it's very similar, then listing differences like GPIOs that could easily be runtime-detectable, doesn't really pin down whether that's a problem or not.

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.

What does "different amount of UART" mean when it is the "same Kirkwood SoC"?

(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.
