Hi ! First, you don't always need one. The kernel will be happy without a device node, unless you want to also represent some devices below that bridge for some reason (such as providing the driver with specific properties from the FW), or your interrupt routing for devices below the bridge doesn't follow the standard PCI swizzling. If you really want to represent it, let me know, I'll try to cook up an example for you tomorrow. You may want to read the Open Firmware PCI binding too which contains all the explanation but it can be a tedious read :-) Cheers, Ben. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
