Both in the Nvidia tarball and in our upstream based package builds, u-boot.bin and u-boot-dtb.bin are identical. Since some time u-boot-dtb.bin gets copied over as u-boot.bin for consistency upstream. Should this work with the vanilla upstream files, or do they need any headers or signatures or something? Do any of you have that upstream version booting successfully, or might it be an upstream U-Boot regression? I was so far assuming it's a user error, so haven't tried bisecting yet.
