This series of patches are based on the patch of Peng Fan: https://patchwork.ozlabs.org/patch/422756/
Patch 1 is the originally patch from Peng Fan, Patch 2 and 3 add minor changes to 1 and patch 4 adds the ECC strength calculation to tools/mxsboot to be aligned with the changes made in patch 1 to 3.
Instead of hard-coding every possible oob size / ECC strength combination calculate the ECC strength dynamically to be aligned with the Linux Kernel MTD NAND driver. Also adds the calculation to tools/mxsboot to be aligned with the U-Boot MTD NAND driver.
Obviously, we have some code redundancy here in mxs_nand.c and mxsboot.c.

Peng Fan (1): mtd:mxs:nand calculate ecc strength dynamically

Tried this patches on the aristainetos2 board. UBI on the nand works nice with this patches, so:
