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.

as well.

P.S.: Wolfgang: Sorry if I missed anything. Do I have to do anything 
more to get above patches applied? Thanks.
