It does complicate maintenance though.  I think all of mips ultimately
uses register_pci_controller() and pcibios_scanbus().  Neither really
contains anything mips-specific, so they duplicate a lot of the code
in pci_host_probe().  Oh well, I guess that's part of the burden of
supporting old platforms forever.

 FWIW new MIPS hardware continues being manufactured and if there is 
anything needed to clean up in generic MIPS/PCI platform code, then that 
can certainly be scheduled, subject to developers' resource availability.  
Individual MIPS platforms may vary of course, and with the solely legacy 
ones it will depend on the availability of hardware and engineers willing 
to maintain it.
