You can read doc/README.fdt-control to understand how dts is compiled
to dtb and used by U-Boot.

zboot is used to load linux kernel while a typical x86 kernel does not
require dtb (although linux x86 supports device tree as its
configuration source). And you seems to be confused by dtbs. The dtb
U-Boot is using is not the same one passed to linux kernel on
arm/powerpc.
