The entire notion of a "primary" PCI bus is due to a Linux flaw. If we did put it in the device tree, it should be something like "linux,primary-phb". But since Linux can tell from the node's children, there doesn't seem to be much point. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
