From the examples it looks like the reg values are unique even across clusters. I wonder whether we should be describing this at all in the device tree given that the topology is discoverable in registers... though that applies to the PowerPC CPUs as well. :-) -Scott -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
