YH,
I found that moving my changes to the latest LinuxBIOS source makes a
difference. Now the device tree entries magically are put on a more correct
bus. But LinuxBIOS uses different busses depending on how I number the
devices. If I number the PCI devices to power up defaults, then the device
table uses bus 1 for the first CK804 and 3 for the second. If I number them
with the bumped up device numbers given by incoherent.c then it uses busses 1
and 2. I would assume that the Config.lb file would use the device's power up
default values?
I'm dumping the device tree in device.c after "Devices initialized" with
printk_info("Dev tree...\n");
for(dev = all_devices; dev; dev = dev->next) {
bus = dev->bus;
printk_info("%s bus %d link %d ", dev_path(dev), bus->secondary,
bus->link);
printk_info(" sibling %s ", dev_path(dev->sibling));
printk_info(" next %s\n", dev_path(dev->next));
printk_info(" vendor %x ", dev->vendor);
printk_info(" on_mainboard %x ", dev->on_mainboard);
printk_info(" enabled %x ", dev->enabled);
printk_info(" have_resources %x ", dev->have_resources);
printk_info(" initialized %x\n", dev->initialized);
}
printk_info("End of tree\n");
Thanks.
Steve

OK, that makes sense. So how do I specify bus 1 and 3 in the Config file?

the first one is right.
bus 2 is leave for bus under your master ck804 pci bus behind pci bridge 1:a.0
