Hello,
I am quite new on this mailing list. I have tried to build u-boot with the last EABI toolchainfrom codesourcery (arm-2007q1-10 version).
Which board?
For an AT91SAM9263EK board. I am adding AT91 evaluation kits support to u-boot 1.2.0 and I did some tests which several EABI compiler : codesourcery , open embedded and buildroot. It seems when there is a 64 bits division the compiler refers to "_udivdi3" which is not implemented into "u-boot/lib_arm/" library and then try to link with libgcc from compiler :
