Hello list,

I try to use the linux-fslc 4.9.17 kernel but the gpmi-nand drivers
seems not to work anymore for my nand flash.  Before I used successfull
the linux-fslc 4.4.x with ported gpmi-nand driver from the 4.1-2.0.x-imx
branch. Something in the mtd infrastructure changed so I can't use the
old gpmi-nand driver anymore.

Some clue how I get the current gpmi-nand driver working?
I get the following errors on booting:
