 *
 * Process a PFI (partial flash image) and write the data to the
 * specified UBI volumes. This tool is intended to be used for system
 * update using PFI files.
 *
 * 1.1 fixed output to stderr and stdout in logfile mode.
 * 1.2 updated.
 * 1.3 removed argp parsing to be able to use uClib.
 * 1.4 Minor cleanups.
 * 1.5 Forgot to delete raw block before updating it.
 * 1.6 Migrated to new libubi.
