It might be better to name the selector "OFW" to be consistant with the directory name, ofwdump, etc.

sys/arm/arm/gic.c
1215

This should be in gic_fdt.c

sys/dev/ofw/ofw_bus_subr.c
113

Extra space before strcmp and "OF" should be BUS_LOCATOR_OF and defined in sys/bus.h

120

return (bus_generic_get_device_path(...));
