ppc platform for AMCC-440EPx - ELDK to the rescue

Could you provide an explanation between the two architectures in the ELDK?
I am also using a Sequoia "spin off" and am trying to determine why I would
want to use the "powerpc" architecture vs. the "ppc" architecture.

This is not exactly correct. Actually it supports both.

You miss the fact that the ELDK has full support for arch/powerpc,
and that some board configurations in our kernel (for example, all
MPC5200 based ones) are available in arch/powerpc configurations
But then - what's the difference? All it takes is a redefinition of
the ARCH envrionment variable in your shell...

I've got a bad feeling about this.
