This is generally applicable only to NAND flash devices with ECC
capability. It is ignored on devices lacking ECC capability;
i.e., devices for which ecc_strength is zero.

+Description:
+ The size of ECC step which is used for ECC.
+ Note that some devices will have multiple ecc steps within each
+ writesize region. See more in the ecc_strength above. This will
+ always be a non-negative integer.
We add a new sys node for ecc step. So update the ABI document about it. Signed-off-by: Huang Shijie <b32955@freescale.com> --- Documentation/ABI/testing/sysfs-class-mtd | 10 ++++++++++ 1 files changed, 10 insertions(+), 0 deletions(-)
