[PATCH V4 0/3] mtd: use the full-id as the keyword for some nand chips

[Huang Shijie <b32955@freescale.com>]

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.

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 4 Toshiba nand chips for the full-id case
  mtd: add the support to parse out the full-id nand type
