May I ask a different question:

* sharing more source code between arm26 and arm32 seems good to me.
* modularizing source code, so that you don't get lost in nested #ifdefs
  when changing the kernel, seems good to me.

But why do we need to split ports? The result is that we have to build
the distribution N times, while 90% of that code is shared. Where 90% is:

- the MI kernel code.
- most of the CPU specific kernel code

It would be more wise, IMHO, to work on the installation process so that
it installs the right kernel for the target machine, the right booter, and
the right /etc/ttys (actually, if only Shark had wscons...)

This way we could build all of the arm32-$X distributions in one run, using
the fastest machine available (be it a Shark/EBSA/other-Strongarm with fast
disk, or a fast Alpha/PentiumV with a cross toolchain).

Whoever wants to split ports even more should device a release building
process that allows reusing the 90% objects already build on, say, some
Strongarm build slave for building the, say, RiscPC kernel and install medi=
a.

The m68k folks will be very thankful, too.
