I just ran into a problem with current U-Boot on Kilauea and device tree enabled Linux kernel (arch/powerpc). After updating U-Boot the kernel doesn't boot anymore:

Before updating U-Boot I am able to boot exactly this kernel/dtb combination without problems:

Any ideas?
The image got overwritten during decompression. Try loading the image at a higher address.
