I ever submitted a patch to use the full-id as the keyword for
some unparsable nand chips. 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
