This is the second tries. 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. So it is time to add some new fields to the nand_flash_dev{}, and update the detection mechanisms. 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 a new table for the unparsable nand chips mtd: add the new detection method for the unparsable nand chips drivers/mtd/devices/doc2000.c | 2 +- drivers/mtd/devices/doc2001.c | 2 +- drivers/mtd/devices/doc2001plus.c | 2 +- drivers/mtd/nand/nand_base.c | 35 ++++++- drivers/mtd/nand/nand_ids.c | 217 +++++++++++++++++++++---------------- drivers/mtd/nand/nandsim.c | 2 +- drivers/mtd/nand/pxa3xx_nand.c | 2 +- drivers/mtd/nand/sm_common.c | 61 +++++------ include/linux/mtd/nand.h | 9 ++- 9 files changed, 201 insertions(+), 131 deletions(-)
