Thankfully, the recent uboot versions now allow the ID passed to be
configurable via its scripts, rather than being compiled in, so this
means compile time mistakes can be easily corrected without reflashing
the boot loader.  I'm not involved with uboot at all, so I couldn't
tell you which versions are what.

But everything Marc says in his reply is correct.
