I was planning to convert CHRP, PMac, and PReP to CONFIG_GENERIC_PPC32 in
2_4_alt (blindly as I have no hardware to test on, just make it compile), then
find some volunteers with the hardware to test the new 2_4_alt, and if it works
make a patch for Paulus.

Mortal, not moral.

I'm not going to touch K2 outside of 2_4_alt. I would say Adirondack can be
moved to CONFIG_GENERIC_PPC32 as owned or not, the port currently in 2_4_devel
does not support any ROM other than StarMON anyway. But I really don't care,
I've got it in 2_4_alt to prove my generic config framework, and I couldn't
care less what happens to the SBS ports in the public tree as I have no loyalty
to them any more.

We would only need a special ppc_serial module when the serial driver is a
module and the machine has hard-wired serial ports. This would be a rare case,
on most machines with hard-wired serial ports one of them is the console and
the serial driver must be compiled in. Those board ports will simply call
early_serial_setup() from <board>_arch_setup as I currently do in 2_4_alt.

Which is exactly what I have in 2_4_alt right now.

Yes, sort of. When you see the implementation you'll see what I mean.
