When you have an update system and a regular system on the same filesystem then I would expect an additional bootspec entry for the update system. > Another use-case could be a dynamic devicetree-overlay handling.

Board code can register overlays already, there's no need for bootspec to do that. Overall overwriting bootspec variables somewhat contradicts the whole purpose of bootspec. I don't like that very much, so you'll need very good reasons to get this through ;) Regards, Sascha -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
