Your U-Boot version shows the version is U-Boot SPL
2016.09-rc2-gc347b70c408b which is a couple years old.  Can you try
2019.01 with those patches I mentioned or the imx branch?  I know
there have been changes to U-Boot over time.

The last of the patches I applied to set the final configuration
settings for my board to boot from NAND are here:
http://patchwork.ozlabs.org/patch/1024016/

I don't know if that helps your board or not.
