Hi John,

Thanks for your help. I found the reason for my issue. I defined the
pinctrl information under the "soc" next to "nfc" entry in
sunxi-a20.dtsi which was messing it up.

I moved them inside the "pio" dtsi block and NAND is detected now.
Though almost all blocks are reported as bad-blocks.  I am thinking
that it's happening as I don't have partition information defined in
DTS. Do you think that this is the reason for bad-blocks reporting?

Regards,

Fawad Lateef
