... and also replaces pci_enumerate_bus_generic() with a MD function
that walks along the OF device tree and enables the device bevore
calling pci_probe_device. At least as I understand this code.=20
Meanwhile I noticed that macppc solves this problem by walking along the
OF device tree in pci_attach_hook() and enabling the devices according
to the information from the OF.=20
Ofppc is split up in different platforms. pci_enumerate_bus() is global
for the port, but pci_attach_hook() is speciffic for the platform. This
way it is possible that every platform supplies its own, platform
speciffic code to enable the devices. This may be more appropriate for
ofppc. (?)=20
I think I have to learn more about Openfirmware now. ;-)=20
