mtd_blktrans_ops->release() should return void

2013-05-06T01:31:22Z

Both existing instances always return 0 and even if they didn't, the value would be lost on the way out. Just don't bother... Signed-off-by: Al Viro

mtd: nand: subpage write support for hardware based ECC schemes

2013-04-05T12:22:59Z

This patch adds support for subpage (partial-page) writes when using hardware based ECC schemes. Advantages: (1) reduces storage overhead when using file-systems like UBIFS, which store LEB header at page-size granularity. (2) allows independent subpage writes, thereby increasing NAND storage efficiency for non-page aligned data. + updated cafe_nand and lpc32xx_mlc NAND drivers for change in chip->write_page interface.

mtd: nand_ids: improve LEGACY_ID_NAND macro a bit

2013-04-05T12:21:41Z

Notice that all the flashes belonging to the "legacy ID" class have 512 bytes NAND page. This means we may simplify the 'LEGACY_ID_NAND()' macro as well as the NAND ID table a little. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: add new fields to nand_flash_dev{}

2013-04-05T12:20:29Z

As time goes on, we begin to meet the situation that we can not get enough information from some nand chips's id data. Take some Toshiba's nand chips for example. I have 4 Toshiba's nand chips in my hand: TC58NVG2S0F, TC58NVG3S0F, TC58NVG5D2, TC58NVG6D2 When we read these chips' datasheets, we will get the geometry of these chips: TC58NVG2S0F : 4096 + 224 TC58NVG3S0F : 4096 + 232 TC58NVG5D2 : 8192 + 640 TC58NVG6D2 : 8192 + 640 But we can not parse out the correct oob size for these chips from the id data. This patch adds some new fields to the nand_flash_dev{}: @id_len: the valid length of the id data. See the comments in nand_id_has_period() @oobsize: the oob size.

mtd: introduce a macro for max NAND ID sequence length

2013-04-05T12:15:06Z

Introduce a helpful macro for the maximum NAND ID sequence length instead of using the "8" magic number. Signed-off-by: Artem Bityutskiy Acked-by: Huang Shijie Signed-off-by: David Woodhouse

mtd: nand: use more reasonable integer types

2013-04-05T12:15:00Z

Use 'unsigned int' instead of 'unsigned long' in the NAND chip description data structure, because 32-bits is more than enough for our purposes. We do not need 64-bits, which is what we end up on 64-bit architectures. We declare many instances of this data structure, so this should help saving some amount of memory.
