Can you please check if the generated u-boot-dtb.img contains a IVT
table appended in the end of the image?

The mx6slevk_spl_defconfig target also generates SPL + u-boot-dtb.img
but I have to use the u-boot-ivt.img binary instead. In my case
u-boot-dtb.img does not includes a IVT table.

Best Regards,
Breno Lima
