The Fine Manual (http://www.denx.de/wiki/view/DULG/UBootImages) isn't very  
forthcoming, sadly;

"U-Boot operates on "image" files which can be basically anything,  
preceeded by a special header; see the definitions in include/image.h for  
details; basically, the header defines the following image properties

* Target Operating System
* Target CPU Architecture
* Compression Type
* Load Address
* Entry Point
* Image Name
* Image Timestamp"

I suspect taking this apart may be a little involved.
