From: Frank Rowand <frank.rowand@xxxxxxxx> This series is a different implementation to achieve the goals of https://lore.kernel.org/r/20220623105044.152832-1-clement.leger@xxxxxxxxxxx In order to apply overlays or create new nodes under the root node, the kernel expects of_root to be set. On some system where a device-tree was 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. This series modifies init/main.c. It was not clear to me whether to add Linus to the distribution, or if the change should flow through Rob. (I did not add Linus.) Frank Rowand (2): of: create of_root if no dtb provided of: unittest: treat missing of_root as error instead of fixing up drivers/of/Makefile | 2 +- drivers/of/fdt.c | 19 ++++++++++++++++++- drivers/of/unittest.c | 16 ++++++---------- include/linux/of_fdt.h | 2 ++ init/main.c | 2 ++ 5 files changed, 29 insertions(+), 12 deletions(-) -- Frank Rowand <frank.rowand@xxxxxxxx>
