[U-Boot-Users] Current U-Boot doesn't boot device tree enabled kernel anymore

[Stefan Roese <sr@denx.de>]

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:

=> run net_nfs_fdt

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