Hi Artem & Brian:
> In order to implement the NAND boot for some Freescale's chips, such as
> imx23/imx28/imx50/imx6, we use a tool (called kobs-ng) to burn the uboot
> and some metadata to nand chip. And the ROM code will use the metadata to
> configrate the BCH, and to find the uboot.
>
> The ECC information(ecc step size, ecc strength) which is used to configrate
> the BCH is part of the metadata. The kobs-ng can gets the ecc strength from
> the sys node /sys/*/mtdX/ecc_strength now. But it can't gets the ecc step size.
>
> This patch set is used to export the ecc step size to user applications.
> With this patch set, the kobs-ng can gets the ecc step size now.
>
> v1 --> v2:
> [1] rename the ecc_size to ecc_step.
> [2] rebase on the latest l2-mtd.
