That's not enough in some cases. Factory engineers
need CRC32 checksum of a ROM image for programming 
verfication. Besides,a stuff like U-Boot/Kernel/
Rootfs combination cannot be checked by mkimage -l. 

So seems an utility which can check the image's 
CRC32 checksum is better. I used to download the 
stuff to RAM in u-boot and got the result with
crc32 command:-)
