We should split this up into two functions: barebox_update_handler_exists_for_name() and barebox_update_handler_exists_for_devpath() *). Fastboot would only need the latter and the barebox_update command would use both, possibly barking when both a name and a device is given (as otherwise we would have to check for name <-> devpath conflicts) Sascha *) I'm open for better names ;) -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
