Does "up" "across" control something now?
cpu k8 "cpu0" register "across" = "{ .chip = &amd8131, .ht_width=16, .ht_speed=600 }" end

You might need to specify the bridges/busses in Config.lb. I know the current code works and can handle this.
Does anyone can help on this ?
Without something like a serial console trace so that the details of what are going on are clear I don't know.
Please see that attached log. As you ca see the HyperTransport scan is not actually done in northbridge.c:amdk8_scan_chain(). It only prints the message before and after the for loop but skip the loop.
Please reread my hunch below. It looks like I nailed it on the head. The fact that the first pci_scan_bus shows devices below 0x18 is confirmation of this.
mainboard_operations needs to specify amdk8_scan_root_bus.
What exactly are you talking about ? It is amdk8_scan_root_bus in ibm/e325/mainboard.c.
static struct device_operations mainboard_operations = { .read_resources = root_dev_read_resources, .set_resources = root_dev_set_resources, .enable_resources = enable_childrens_resources, .init = mainboard_init, .scan_bus = amdk8_scan_root_bus, .enable = 0, };
Hmm. So it is there.
For some reason it is not being called. A missing chip.h perhaps?
My old copy of that code does: max = pci_scan_bus(&root->link[0], PCI_DEVFN(0x18, 0), 0xff, max);
So it starts at device 0x18 (The first cpu) and works down. That is not happening so that code is not being called.
I don't know why/how it is failing except possibly for fragility in the config tool. But I observe it is not.
