Message-ID: <1206616392.23794.33.camel@localhost> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Hi Guys, I ask you fro a comment regarding the new image format. I'm studying the mkimage code (and image.c file) to understand how new image works. I have the following observations/questions: - The mkimage calculate hashes before that timestamp is added to image. is it better exchange the order of these operations (before add timestamp then calculate hashes)? - Does the new format assure that the complete image (_all_ sections, images, ramdisks, configurations, blobs) are covered by at least an hash value? should mkimage add at least a hash value for the root node?
