Subject: [PATCH 0/2] of: populate of_root_node if not set (alternate)
Date: Thu, 23 Jun 2022 22:43:25 -0500 [thread overview]
Message-ID: <20220624034327.2542112-1-frowand.list@gmail.com> (raw)
From: Frank Rowand <frank.rowand@sony.com>
This series is a different implementation to achieve the goals of
https://lore.kernel.org/r/20220623105044.152832-1-clement.leger@bootlin.com
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
