At the same time, I'm also trying to deduplicate the FDT and OFW code, since they are implementing many of the same interfaces and specifications. As part of that, I've adapted the MPC85XX PCI driver to use the generic ofw_pci code, which gives a quite substantial reduction in the driver and also substantially improves its robustness to variations on the device tree setup:

I had quite a bit of problem with PCI and the P1020WLAN eval board, which is based on the MPC85XX processor 'class'. Unfortunately right at the moment I've had to return to updated my OpenWRT linux environment, so perhaps next week I can 'test' what you have on my hardware.
