It is confusingly named, but it is required on the host bridge OF node. The spec says ' .. corresponding to a device that implements a PCI bus', which includes the host bridge. The key element is that it must be present on the node that introduces the PCI 3 dword address encoding scheme, and then on all nodes below it that use the 3 dword scheme. Otherwise Linux common OF PCI code does not work properly.
