I am upgrading from an older 3.x kernel and trying to use that device tree on a custom board based on imx6, new kernel is Linux-4.9.88
I have tried to add the properties that 'should' fix this (fsl,legacy-bch-geometry; fsl,use-minimum-ecc), but it does not work, I get the same errors. The device is flashed using mfgtool and I'm using Uboot 2009, I do not want to upgrade u-boot because I have this old device tree so I do not know if it will work...
Device tree node for nand:
gpmi-nand@00112000 {
