Re: [U-Boot] [PATCH] JFFS2: Fix undefined reference to `__aeabi_uldivmod' error

27 Oct 2013

2013/10/27 Wolfgang Denk wd@denx.de:
...
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'
I recently noticed a similar problem on MIPS too:
fs/jffs2/libjffs2.o: In function `jffs2_get_list':
jffs2_1pass.c:(.text.jffs2_get_list+0x5c): undefined reference to `__udivdi3'
Your patch solves it, thanks.

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.
