As my previous said, can do partial revert? Just add back property under
gpmi and keep nand@0 node.

For example

--- a/arch/arm/boot/dts/nxp/imx/imx6qdl-skov-cpu.dtsi
+++ b/arch/arm/boot/dts/nxp/imx/imx6qdl-skov-cpu.dtsi
@@ -260,14 +260,10 @@ fixed-link {
&gpmi {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_gpmi_nand>;
+ nand-on-flash-bbt;
#address-cells = <1>;
#size-cells = <0>;
status = "okay";

Remove "- nand@0" part. You can use "git add -p" to do that.
