[U-Boot] Missing __udivdi3 for ARM

[J.C. Wren]

I enabled CONFIG_YAFFS2 for ARM, and got the following message:
/home/user/u-boot/fs/yaffs2/yaffscfg.c:185: undefined reference to
`__udivdi3'

I know some other math routines have been fixed, is there a patch for this
one?  A few minutes of searching found some things from 2007-July, but it
seemed to be refactoring the code rather than adding the function.

Thanks,
