When trying to build U-Boot under Buildroot and OpenEmbedded,
These probably count to the tool chains with "broken" ARM cross compilers.
Maybe, Buildroot is even more broken, if you try to use an external toolchain and I would be surprised if openembedded is better. In the end, noone wants to mess around with one compiler per application so it is better if a small fix to u-boot can be applied.
When linking u-boot the linker seems to use the div0 from the C compiler libgcc instead of the u-boot div0.
Try setting USE_PRIVATE_LIBGCC=yes in your envrionment, like
USE_PRIVATE_LIBGCC=yes make ...
I have done two fixes to make it build with openembedded. 1) Define "raise" in libarm/board.c which calls hang. 2) Changes mapi to "-mapi=aapcs-linux" in cpu/arm926ej-s/config.mk Some toolchains want to keep apcs-gnu I guess.
Best regards,
