Changelog:
+ v2.4 - added ":image" definition for parameter file, this allows
+ to use a complete sysupgrade image without any kernel size check
v2.3 - allow jffs by adding its magic number (0x8519)
added parameter option -i to ignore unknown magic numbers
v2.2 - fixed checksum byte calculation for other versions than 0x2019
