With Macronix reusing the same ID for different flash chips it makes software support for different features really hard. And with even with the SFDP being the very same, it's impossible to distinguish them during auto probing. -michael --0841a41031df2269291596afdfdff64d5d5d3341d99f2cab1d8ce3e79068 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iKgEABMJADAWIQTIVZIcOo5wfU/AngkSJzzuPgIf+AUCad9jexIcbXdhbGxlQGtl cm5lbC5vcmcACgkQEic87j4CH/hQ4AGAhv7ADzlPatwb7nsE3KXxWsIOPAkA/RLM VSbJW1+OabkBm1oqr2gR9bOAajOeA2R/AX9Z2ab7ZCeODBX4LCCQX+w+hG2ZF6T5 3JJUwoNcte4unjUd3P4tfwDkWfCEdE2Q254= =o8Xe -----END PGP SIGNATURE----- --0841a41031df2269291596afdfdff64d5d5d3341d99f2cab1d8ce3e79068-- --===============3266870448866720653== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/ --===============3266870448866720653==--
