What is the purpose of padding the load address to 64 bits?

The reason I'm asking is that we encountered a bug with that when creating a 
u-boot image on a 32-bit host machine: the mkimage tool will only parse the 
first 8 hex digits and then inserts the wrong load address into the uImage.

Bye,
                Maarten
