No, that's not a MontaVista specific issue. I have an other toolchain and it has similiar issues. Nor is it an ARM specific issue.
nand_utils.c uses 64bit division, and if you use stuff from nand_utils.c you may get these issues. So solution is to make U-Boot independent from toolchain for 64bit division used in nand_utils.c as already done with other math helpers in lib_arm.

P.S.: Wolfgang: Sorry if I missed anything. Do I have to do anything more to get above patches applied? Thanks.
I can post a proper RPM .spec file and all required patches for GCC 4.2.0 based toolchain (arm-elf, for standalone applications e.g. U-Boot with almost complete multilib less EP9312 FPU) if somebody wants them...

But something breaks if I change the dvevm.h file to #define CFG_USE_NAND. The compile breaks at the end with warnings (warnings that cause make to error out). They have to do with "function '__udivsi3'" being redifined (and the warning that stops the compile is this: "arm_v5t_le-ld: Warning: size of symbol `__udivsi3' changed from 152 in lib_arm/libarm.a(_udivsi3.o) to 496 in /opt/montavista-arm-v4.00-alt/pro/devkit/arm/v5t_le/bin/../lib/gcc/armv5 tl-montavista-linuxeabi/3.4.3/libgcc.a(_udivsi3.oS)"
I got this same error last time I made a quick and dirty attempt to get 1.2.0 to compile for Davinci.
