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. So it is time to add some new fields to the nand_flash_dev{}, and update the detection mechanisms. v3 --> v4: [1] rewrite the code based on the latest l2-mtd. [2] add the full-id nand in the nand_flash_lds. v2 --> v3: [1] remove the duplicated header. [2] remove the field "ecc_len" in nand_flash_dev{}. [3] fix some coding style warnings. [4] add more comments Huang Shijie (3): mtd: add new fields to nand_flash_dev{} mtd: add 4 Toshiba nand chips for the full-id case mtd: add the support to parse out the full-id nand type drivers/mtd/nand/nand_base.c | 36 +++++++++++++++++++++++++++++++++--- drivers/mtd/nand/nand_ids.c | 15 +++++++++++++++ include/linux/mtd/nand.h | 4 ++++ 3 files changed, 52 insertions(+), 3 deletions(-)
