I dunno, if the firmware affects the functionality of the hardware in a way that cannot be detected from the operating system at runtime how else is it supposed to deal with that? The devicetree is supposed to describe hardware, yes, but at a certain point the line between firmware and hardware is invisible :) Not describing software is mostly about not using it to determine software policy in the operating system. --cEg17b20MxyCi/dL Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRh246EGq/8RLhDjO14tDGHoIJi0gUCZeDPuQAKCRB4tDGHoIJi 0oklAQCb9liXgCtU0yqoCxGYrPtfMDdWh7iUxPWsScbIPS343AD/c6Wr2hVOtmtB qj/WEDA/Sdh/5pt/pXxfhjnLYJ4shA4= =+qJ3 -----END PGP SIGNATURE----- --cEg17b20MxyCi/dL--
