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.
v5 --> v6: [1] add back the id_len as Brian's suggest. [2] use id_len to check the full id nand or not. [3] change the new fields oob_size/id_len to "uint16_t" type. [4] misc
v4 --> v5: [1] remove the id_len field. [2] based on Artem "mtd: nand: use more reasonable integer types" [3] add more comments.
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 the support to parse out the full-id nand type mtd: add 4 Toshiba nand chips for the full-id case
