As we are pushing for verified boot I am using the Flat Image Tree (unifying kernel image, device tree blob, ...) to describe my system. U-Boot can load the ITB file and tries to start the kernel but the system hangs after this message.

That looks plausible, but ...

That looks like it's copying the kernel to address 0, which isn't RAM on 
this system. You'd need to track down why the wrong address is being used.

BTW, you may want to contact linux-tegra-bugs at nvidia.com for support 
with L4T. That said, this aspect of L4T U-Boot should be identical to 
upstream U-Boot, since the L4T version is so close to upstream now.
