| |
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.
This patch just adds some new fields to the nand_flash_dev{}: @id[8] : the 8 bytes id data. @id_len: the valid length of the id data. @oobsize: the oob size.
