All warnings (new ones prefixed by >>):

warning: (M68K) selects PCI_GENERIC_SETUP which has unmet direct dependencies (MMU)

I can't seem to find this dependency of PCI_GENERIC_SETUP on MMU?

It looks like M68K only includes the PCI Kconfig entry when MMU is enabled.  I
moved the select around a bit and it builds the config that was failing for me.

The updated patch is threaded.
