2013-04-11	4c2bdc8 Browse files » nand_base: detect more ONFI flash ... if the flash has a known type, the ONFI detection won't occur and thus we may not detect the right parameters. By testing both namd and pagesize, as done in the kernel, we can detect ONFI flash with know IDs. As an example on an i.MX53 board : - without the patch : NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3 (Micron NAND 1GiB 3,3V 8-bit), page size: 4096, OOB size: 128 - with the patch : ONFI flash detected ... ONFI param page 0 valid NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3 (Micron MT29F8G08ABACAWP), page size: 4096, OOB size: 224 in the first case the OOB size is wrong.

2013-03-09	c3ccb2c Browse files » mtd: nand: Add bbt parameter ... The information which kind of bbt (if any) is used is hidden somewhere in the NAND layer. Expose it to a device parameter to make it detectable and visible during runtime. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 9 Mar 2013
2013-03-04	c26ef82 Browse files » mtd: Add parameter to allow erasing bad blocks ... While erasing bad blocks is a potentially dangerous operation it is sometimes needed during development or when some foreign code has touched the flash. This patch adds a device parameter 'erasebad' to allow erasing bad blocks. Since this is not wanted during production this is behind a Kconfig option.

2012-09-16	7d4d295 Browse files » mtd: nand: extend NAND flash detection to new MLC chips ... Some of the newer MLC devices have a 6-byte ID sequence in which several field definitions differ from older chips in a manner that is not backward compatible. This method is already used in the Linux Kernel.

2012-08-03	85f4fe3 Browse files » mtd nand: implement buswidth detection ... This introduces a new NAND_BUSWIDTH_AUTO flag which can be used to automatically detect the nand buswidth. The id is always read in 8bit mode. An additional callback is needed to switch the nand controller into 16bit mode. This currently depends on a safe read_byte (always) and read_buf (for onfi-only flashes) callback. It has been tested on OMAP, but is not something that generally works. For this reason the existence of the set_buswidth callback is used to determine whether we are able to do autodetection or not.

Change "page_shift" references in the core, which are purely NAND, into mtd->writesize which is MTD generic. Rename all "info" (struct mtd_info) into "mtd". Also provide a parameter to add_mtd_device() so that legacy nand devices still appear as nand<N>.
