I wish I could.  At least this new "noload" option would make uImage 
compatible with this.  That won't help existing u-Boot installations 
though, which is why I didn't post that patch series yet as I still 
haven't found a good fallback.

Doesn't it use AUTO_ZRELADDR?  With the newer u-Boot, you'd just load 
uImage to whatever address and u-Boot won't mess with it.
