This is a new flash installer framework for the X1000 targets. A bunch of this code is *UNTESTED* but there is an external test harness which allows the library to be built and tested on a PC. Once tests are written and the bugs are ironed out this framework will replace the existing installer code. New features: - Update tarballs are MD5-checksummed to guarantee integrity. - The flash map is no longer fixed -- updates are self describing and carry a map file which specifies the areas to update. - Can take full or partial backups with checksums computed on the fly. - Supports an additional verification mode which reads back data after writing to ensure the flash contents were not silently corrupted.
