Yes, I did just that, but as of v4.6-rc6, I am seeing a bunch of
undefined references while doing so:

arch/mips/pci/built-in.o: In function `pcibios_enable_device':
(.text+0x550): undefined reference to `pcibios_plat_dev_init'
arch/mips/pci/built-in.o: In function `pcibios_init':
pci.c:(.init.text+0x6c): undefined reference to `pcibios_map_irq'
pci.c:(.init.text+0x78): undefined reference to `pcibios_map_irq'

and this makes perfect sense because arch/mips/pci/pci.c is referencing
those functions, while I did not add anything for BMIPS_GENERIC.

At this point, I would very much prefer that the MIPS/Linux kernel did
not rely on the different machines to provide those implementations
(though it definitively is not a big deal to add them, it just feels
unnecessary), I will try to cook a patch for that and provide dummy
fallbacks.

Thanks!
