We will start building overlays for platforms soon in the kernel and would need fdtoverlay going forward. Lets start building it. The fdtoverlay program applies (or merges) one or more overlay dtb blobs to a base dtb blob. The kernel build system would later use fdtoverlay to generate the overlaid blobs based on platform specific configurations.
