Yes, well, but no. The location code is useful as a geographical location: slots and devices are physically labelled with stickers so you can tell which is which. Handy when you have to unplug stuff. By contrast, the device-tree full_name is mostly just gobldy-gook, with some crazy phb numbering in there that, after four years of staring at them, I still can't reliably do anything useful with. Location codes are nice. --linas - 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/
