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
