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.

Best regards,

Thomas
