This error seems to be coming from src/soc/intel/apollolake/Makefile.inc:
files_added:: $(IFWITOOL)
»       $(IFWITOOL) $(CONFIG_IFWI_FILE_NAME) create -f
$(objcbfs)/ifwi.bin.tmp
»       $(IFWITOOL) $(objcbfs)/ifwi.bin.tmp delete -n OBBP
»       $(IFWITOOL) $(objcbfs)/ifwi.bin.tmp replace -n IBBP -f
$(objcbfs)/bootblock.bin -d -e IBBL
»       $(CBFSTOOL) $(obj)/coreboot.rom write -r $(CONFIG_IFWI_FMAP_NAME)
-f $(objcbfs)/ifwi.bin.tmp --fill-upward

Did you ensure that CONFIG_IFWI_FILE_NAME is set correctly to point to your
IFWI image and that your IFWI image is actually valid?

You can run "ifwitool <IFWI_IMAGE> print" to check if you see it printing
the right information.
