We shouldn't be #ifdef'ing externs, since it doesn't matter.  The
pmac/prep/chrp ones were hidden just because the line above was, iirc.

OK.

And the one downside to the GENERIC_PPC32 platform_init, is that we're
back to adding:
#ifdef CONFIG_x
 case _MACH_x:
  x_init(...);
  break;
#endif

And what's wrong with that? It allows the user to make the kernel size vs.
generality trade-off: you can have one machine supported or all of them.

Well, take a look at what the file used to look like in _devel.  It was
around 30-40 lines of that.  Which is not nice to look at.

Which I think Paul was happy to see die :)

But it's necessary, and it's a much better system than what you have now.

Well, it's a much better system if you want to group unlike hardware
together in one kernel. :)

    Add generic PPC32 config, implemented for
    Adirondack, EV-64260A, and K2

Do any of these boards actually have an ISA slot?

The boards I've used for this first implementation don't. But
CONFIG_GENERIC_PPC32 is generic PPC32, not just these boards, and it should be
possible for someone to support a machine with ISA slots under this generic
framework.

Well, if ISA slots exist on the board, and should be working, they
should just work.  And when BenH merges in prep/chrp, it'll be needed.
But the question is do you really want to offer this up on machines
where it's not tested?

Right now it's an ALL_PPC-only
option because it's actually needed for sound on some PReP boxes..

And I'm hoping that some day PReP will be part of CONFIG_GENERIC_PPC32. See
BenH's response about putting CONFIG_ALL_PPC to rest and converting to
CONFIG_GENERIC_PPC32.

Right.
