Description:
Maximum number of bit errors that the device is capable of
- correcting within each region covering an ecc step. This will
- always be a non-negative integer. Note that some devices will
- have multiple ecc steps within each writesize region.
+ correcting within each region covering an ECC step (see
+ ecc_step_size). This will always be a non-negative integer.
In the case of devices lacking any ECC capability, it is 0.
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 a single region covered by ECC, known as the ECC
+ step. Devices may have several equally sized ECC steps within
+ each writesize region.

+ It will always be a non-negative integer. In the case of
+ devices lacking any ECC capability, it is 0.
