You can use dump_image -l to list it.

All that really matters in the end in your '.config' file in the build
directory. You could send that through, perhaps? You are using an old
U-Boot, so you could try moving to the latest version, but it won't
help this problem.

It should be fine. But the real question is why it dies at point, if
you have FIT enabled as you say. I suggest adding 'printf()'
statements to the code in boot_get_kernel() if you are sure everything
else is right.
