Currently, the kernel supports three imx6 boards for the gpmi-nand:
    imx6q-arm2, imx6q-sabreauto, imx6dl-sabareauto.

I am afraid your board is none of them. I doubt your board is not 
correctly configrated with
some timing or signals.

The key issue (i want to emphosis ) is that the current gpmi-nand does 
not support the
subpage operations.

It's a SLC ,or a MLC?
