If you really want to add this (I talked to Philipp before about how I don't think this really does anything useful, but knock yourselves out), please make sure it stays entirely optional for boards that don't use it. CBFS attributes are not free. I think the best way to do that may be to create a make variable (e.g. $IBB_TAG) that is only set to "--ibb" when this feature is enabled (maybe controlled via Kconfig), and is otherwise empty. Then use that variable instead of adding the tag directly in all these places.
