The mpc85xx EDAC code can be configured as a module but then fails to build because it uses two unexported symbols:
ERROR: ".pci_find_hose_for_OF_device" [drivers/edac/mpc85xx_edac_mod.ko] undefined! ERROR: ".early_find_capability" [drivers/edac/mpc85xx_edac_mod.ko] undefined! We don't want to export those symbols just for this driver, so make the driver only configurable as a built-in. This seems to have been broken since at least commit c92132f59806 ("edac/85xx: Add PCIe error interrupt edac support") (Nov 2013).
