[U-Boot-Users] Accessing mkimage checksum

Because I want to write it through the uClinux MTD layer, which has nothing to 
do with u-boot, other than the fact that the flashing utility needs to 
calculate a checksum and verify it against the package, which is  
the "ubootian" format created by mkimage.

This is really a question for both the uClinux and u-boot communities.
If a section of what I'm asking does not apply to your work then please ignore 
it. 

thank you,
