Add adder87x board support to 2.6.x

Greetings all.

This set of patches adds support for the Analogue & Micro Adder87x to Linux.

The port is based on mpc885ads in the 2.6.18-rc4 tree.
The patches are very simple really consisting of a stripped down version of mpc885ads renamed to adder87x*blah, a defconfig and appropriate entries in arch/ppc/Kconfig, arch/ppc/platforms/Makefile and include/asm-ppc/mpc8xx.h.

I've spent a bit of time testing this out, and I'm reasonably happy that this should be useful to others using this development board.

Bryan,

If you're not already on the linuxppc-dev mailing list, you should be. The 'ppc' tree is deprecated and all new work should be happening in the 'powerpc' tree (as in arch/powerpc).

The odds of this being accepted are slim but either way, you should read the mail archive and get involved in the powerpc migration.

Mark

Ah... I saw recent activity in the ppc tree and assumed it was still the place to do 8xx development.

No worries Mark, perhaps the thing to do is to do a board port based on the powerpc tree instead.
