As shown in the following figure, if you enable the
configuration, you can build separate U-Boot dtb with the provided design and you
can find the binary in <plnx-proj-root>/images/linux with the name u-boot.dtb. You can change the name with the
uboot dtb package name option. If you have a dts file to build
a separate U-Boot dtb, then you can use the “uboot dts file path” to provide the
dts/dtsi files with space separation.
