Am I correct in assuming >that this particular internal/external split is Freescale-specific and >not a general OpenPIC thing? Yes it looks like this. I can see this split in all mpc85xx boards and mpc8610 boards from Freescale. There just two boards where I don't see this kind of split: holly & kurobox and I don't the have the reference manual for both of them to check. I also don't have an OpenPIC spec to check there. So from this it looks like e500/e600 thing and FSL only so far. > >-Scott Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
