I assume you use Mike Frysingers precompiled avr32 toolchain. I know
about that warnings and beware, these toolchain produce defective
binaries! The u-boot does not relocate itself properly with these newlib
toolchains (also the atmel provided one).

It's ok so far, the arm-linux toolchain I have do not produce these
warnings. Kan you provide the patch so I will do a runtime test.
