Not necessarily. The DT can be used by U-Boot itself to know which peripherals are available, and how they should be configured. I am not sure there is a U-Boot option to bundle the DT within U-Boot just for the purpose of passing it to the kernel. But I might be wrong, I haven't looked in details at how U-Boot uses the DT.
