It's a EABI problem, see this thread:

  http://lists.denx.de/pipermail/u-boot/2009-September/059896.html

(and the other one referred from here). We don't have a good solution
yet, but you have a hacky patch to revert to the old ABI at the end of
the thread above.


We still haven't found out what's actually causing this. EABI itself
should be fine since Linux works well with it, but something is causing
problems with multiple versions of GCC for U-boot. For now you can use
the patch referred to above. For me, saveenv works fine on OpenRD, so
it should be OK for you as well :-)
