The ELDK uses both arch/ppc and arch/powerpc. I consider them quite reasonable people, and foresee them eventually switching to arch/powerpc over time. In fact, their efforts are a large part of the continued progress of 4xx on arch/powerpc. josh _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
