Compiling device trees
The next step is to build the device tree, or trees if you have a multi-platform build. The dtbs target builds device trees according to the rules in arch/$ARCH/boot/dts/Makefile, using the device tree source files in that directory. Following is a snippet from building the dtbs target for multi_v7_defconfig:
$ make ARCH=arm dtbs[...] DTC arch/arm/boot/dts/alpine-db.dtb DTC arch/arm/boot/dts/artpec6-devboard.dtb DTC arch/arm/boot/dts/at91-kizbox2.dtb DTC arch/arm/boot/dts/at91-sama5d2_xplained.dtb DTC arch/arm/boot/dts/at91-sama5d3_xplained.dtb DTC arch/arm/boot/dts/sama5d31ek.dtb[...]
The compiled .dtb files are generated in the same directory as the sources.
