Make an additional step to add full DM support to mx6cuboxi, including its
support for SPL
With this new configuration SPL image is 50 KB, higher than the
38 KB from the previous version, but it still under the 68 KB limit.

Have you tested boot from eMMC?
You would most likely need to add &usdhc3 to SPL DT for that.
Good point. I haven't tested booting from eMMC as I can only boot from
SD because of eFuse settings. However after re thinking it should be
still possible to test it by keeping SPL on SD and placing U-Boot on eMMC.
Regards,
Walter
