<snip strict aliasing error on gcc-4.4>
I have dug into it and found a way to avoid GCC 4.4 or below to warn about aliasing, by replacing 'struct {}' with 'char[0]' as the 0-byte-size type.
I still have some warnings through, regarding some regions not being declared:
avr32-ld:built in linker script:15: warning: memory region `FLASH' not declared avr32-ld:built in linker script:69: warning: memory region `CPUSRAM' not declared
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 appears 'normal' in that without my patch, the same error occurs; but I'd prefer that you confirm whether you have the same warnings on your side.
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.
Best regards
