While I also enjoyed the flexibility on m68k, some of it was paid for in
terms of increased complexity in head.S and entry.S (and especially head.S
wasn't a bit pretty). I'm not sure how your trouble with the embedded
systems can be solved, we kept separate head.S versions for Macs and other
machines for a while as well because things just got too confusing. Maybe
we need to keep separate versions for embedded and other systems here?

  I think we don't want to get too carried away with pulling things
apart here. Afterall I think we'd all like to be able to continue to
pick up a distro with a bootable kernel that works over a wide variety
of machines instead of 10 different kernels to choose from depending on
which box you've got.

Note that I never said the various CONFIG_* options have to be mutual
exclusive. Enable them all for a generic kernel for a distro, enable what you
need only for a machine-specific kernel.

That's exactly what won't work now. A kernel built for PowerMac won't work
on embedded systems or APUS, and maybe not even on PReP or CHRP.

PowerMac kernels should work on PReP and CHRP as well.

  Now obvoiusly I'm going a little overboard here but hopefully you
might see what I'm saying. Granted embedded boxes aren't going to care
about booting from the install cd but I think the rest of us sure do!

I don't see where we would conflict, all I said was maybe keep embedded
separate. By all means unify the rest if at all possible.

The rest is unified. But it's so unified that I can't get rid of e.g. all
PowerMac-only code when I want to compile a kernel for a CHRP box. Much
PowerMac specific stuff is indeed freed up later when the pmac section is
released, but that's all.
