Subject: [for-linus][PATCH 1/3] bootconfig: Load size and checksum in the footer as le32
Date: Tue, 01 Dec 2020 20:12:25 -0500 [thread overview]
Message-ID: <20201202011309.569371712@goodmis.org> (raw)
In-Reply-To: 20201202011224.839590843@goodmis.org
From: Masami Hiramatsu <mhiramat@kernel.org>
Load the size and the checksum fields in the footer as le32
instead of u32. This will allow us to apply bootconfig to the
cross build initrd without caring the endianness.
