From 2e0c558064ad6c92624a0a826721a83321b227af Mon Sep 17 00:00:00 2001 From: Amaury Pouly Date: Tue, 22 Oct 2013 00:48:33 +0200 Subject: Introduce rbutil/mkzenboot, a replacement for tools/mkzenboot The old tools/mkzenboot has a number of problems: very hard to maintain, poor integration with rbutil. Restart from scratch by recycling all the crypto and descrambling code, rewrite the actual firmware modification part to handle all scenarios in a much clearer way. The code is ready to be integrated into Rockbox Utility, by using the very similar interface to mkimxboot. I copied all the keys from the old mkzenboot, so it can potentially support the older Creative ports, but since this is untested, I prefer not do so at the moment. However, I did add a "mixed" boot option to support the dualboot style used in the older ports.
