    Same here.

    You need both PCI and MIGHT_HAVE_PCI? Don't know but it looks
    like defconfig is missing PCI stuff.. and MIGHT_HAVE_PCI is enough
    here?


 PCI is needed here because board-og.c file depends on pci.o.

It shouldn't though, thus the original use of MIGHT_HAVE_PCI.
The board-og.c machine code supports a number of boards, some of
which don't have a PCI bus (that is they use the KS8695 CPU that
doesn't contain the PCI bus silicon).

I think you want a fix that makes the pci support code in this file
conditional on CONFIG_PCI.
