Building boards that have JFFS2 support enabled will fail when using U-Boot's builtin GCC library, for example like this:
USE_PRIVATE_LIBGCC=yes ./MAKEALL omap3_evm ... fs/jffs2/libjffs2.o: In function `jffs2_1pass_build_lists': fs/jffs2/jffs2_1pass.c:1441: undefined reference to `__aeabi_uldivmod'
This is caused by a u64 / u32 division in jffs2_1pass.c; the problem can be avoided by using do_div() instead of plain division.
