Hello. > Here's my proposal, based in Pekon's latest work. > > This patch removes the flash device bus-width configuration, prior to > the device detection. With this modification, a NAND driver is no longer > able to "force" the device width, and instead can only obtain the detected > bus-width after the call to nand_scan_ident(). ... > Alexander: Could you try this patch and see if it's suitable for your needs? > I think you should be able to use it to set the bus-width, without any need for > a new DT property. You will have to split your nand_scan() call in an initial > call to nand_scan_ident() and a final call to nand_scan_tail(). 16-bit ONFI: ONFI param page 0 valid ONFI flash detected NAND device: Manufacturer ID: 0x2c, Chip ID: 0xca (Micron MT29F2G16ABAEAWP), 256MiB, page size: 2048, OOB size: 64 Scanning device for bad blocks 1 ofpart partitions found on MTD device MT29F2G16ABAEAWP Creating 1 MTD partitions on "MT29F2G16ABAEAWP": 0x000000000000-0x000010000000 : "nand-gpio" 8-bit non-ONFI: NAND device: Manufacturer ID: 0xec, Chip ID: 0x76 (Samsung NAND 64MiB 3,3V 8-bit), 64MiB, page size: 512, OOB size: 16 Scanning device for bad blocks 1 ofpart partitions found on MTD device NAND 64MiB 3,3V 8-bit Creating 1 MTD partitions on "NAND 64MiB 3,3V 8-bit": 0x000000000000-0x000004000000 : "nand-gpio" Cannot test 8-bit ONFI, since have not such chip. --- ��.n��������+%������w��{.n����z�{��ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
