It should fix the problem [1]. Brian, I have a question regarding the extended NAND ids (not full-ids) defined in the nand_ids table. Are they really valid for all vendors? If that's the case, why are we extracting the bus width from the id[3] since we already have this information in the options field? > > [1]http://code.bulix.org/6hjww1-100494 > > -- Boris Brezillon, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
