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. Change-Id: I80cfc48fa78187baa1b1692e8a30ec7137cea37b 2013-10-21 22:48:33 +00:00			`CC=gcc`
