This is usually a sign that I got the dtc wrong somehow.
Here is v2:
struct device _dev15 = {
.ops = 0,
.bus = &_dev8.link[0],
.path = {.type=DEVICE_PATH_PCI,.u={.pci={ .devfn = PCI_DEVFN(0x0,0)}}},
.enabled = 1,
.on_mainboard = 1,
.link = {
[0] = {
.link = 0,
.dev = &_dev15,
.children = &_dev16,
},
},
.links = 1,
.sibling = &_dev20,
.chip_ops = &southbridge_amd_amd8111_ops,
.chip_info = &southbridge_amd_amd8111_info_14,
.next=&_dev16
};
and
struct device _dev16 = {
.ops = 0,
.bus = &_dev15.link[0],
.path = {.type=DEVICE_PATH_PCI,.u={.pci={ .devfn = PCI_DEVFN(0x0,0)}}},
.enabled = 1,
.on_mainboard = 1,
.link = {
},
.links = 0,
.sibling = &_dev17,
.chip_ops = &southbridge_amd_amd8111_ops,
.chip_info = &southbridge_amd_amd8111_info_14,
.next=&_dev17
};
So the amd8111 is a bridge that needs resources.
That said, you said your change fixes it. Does that mean serengeti
works? It's hard to see how given that this is a bridge.
