Wolfgang,

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.  

Thanks,
Dave

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
only.

But then - what's the difference? All it takes is a  redefinition  of
the ARCH envrionment variable in your shell...

Best regards,

Wolfgang Denk

I've got a bad feeling about this.
