You might check that U-Boot is entering select_ramdisk() correctly
when the 'bootm' command runs, and see what happens there. It should
call fit_image_load() to load the ramdisk. I don't see any logging for
that case though - you can add it if you like.

 I cannot see anything wrong with the .its file.
