In order to apply overlays or create new nodes under the root node, the kernel expects of_root to be set. On some system were a device-tree us not provided by firmware (x86 for instance) if CONFIG_OF is enabled, then we will end up with a null of_root. This series add support to create this root node using a builtin dtb and remove the manual creation of the root node done in unittests.c.
