 * http://www.isysop.com/unpacking-and-repacking-u-boot-images-part-2/ part 2 set of python scripts for working with U-Boot image files when phone-hacking. The first script is similar to the U-Boot mkimage tool, only it adds the ability to extract data from existing images. The next two scripts are particularly for WebOS and meta doctor.  These scripts are similar to diff and patch, but they are intended to distribute change instructions for ramdisk image files.  More than just a binary patch, these utilities introduce what I call a copy-patch.  A copy-patch contains instructions for merging one binary file into another without actually containing the contents of either file.  This allows the patch to be distributed without violating the IP rights
