Could you please let me know that, when can we expect generic ECC engine
update in mtd NAND?
Based on that, i will plan to update the ARASAN NAND driver along with your
comments mentioned above under this update,
as you know there is a limiation in ARASAN NAND controller to detect
ECC errors.
i am following this series https://patchwork.kernel.org/patch/10838705/
