This sometimes happens on ARM when you have a new barebox with internal devicetree but want to start an older kernel which needs the ATAG list to start. > > also, at the risk of being overly pedantic, i would distinguish > between the actions of "probing" and "consulting." i would normally > use the word "probe" in the sense of probing for possible devices, not > knowing if they're there or not. Indeed we do not have this kind of probing here, so the term might be misleading. > i would use the word "consult" when > one is reading or processing something that is known to be there, such > as the device tree. How about devices that are instantiated or populated from the devicetree? I never heard the word "consult" in this context. > > some probably silly questions about device trees coming up shortly Hm, most of the time such silly question turn out to be not silly at all Sascha -- 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@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
