Subject: [PATCH 1/3] bootconfig: Load size and checksum in the footer as le32
Date: Fri, 20 Nov 2020 11:29:04 +0900 [thread overview]
Message-ID: <160583934457.547349.10504070298990791074.stgit@devnote2> (raw)
In-Reply-To: <160583933538.547349.272918354455492444.stgit@devnote2>
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.
