We should not add any new hardocded busses here. Please mark them in OF/ACPI.
Unfortunately for us, fsl-mc is conceptually rather like PCI in that it's software-discoverable and the only thing described in DT is the bus "host", thus we need the same sort of thing as for PCI to map from the child devices back to the bus root in order to find the appropriate firmware node. Worse than PCI, though, we wouldn't even have the option of describing child devices statically in firmware at all, since it's actually one of these runtime-configurable "build your own network accelerator" hardware pools where userspace gets to create and destroy "devices" as it likes.
