Please explain abbreviations. What's PBI? CPC? What is "pbl_image_tool.html"? I doubt that a HTML page can be used as tool? And where can this tool be found? And why is it not part of the U-Boot distribution? > +1.

This must be a bad joke. Can you not provide a plain and simple AUTOMATIC way to get this result? some plain stupid command line tool? Something that works as a simple "make XXX" ? So it can be scripted / automatized / used?
