[U-Boot] v2013.10 failed build with jffs2 cmd

[Chris Ruehl]

Dear List,

when I tried to build v2013.10 with the Option: CONFIG_CMD_JFFS2
using linao tool-chain 2013.09 (and earlier) I run into the well known problem

  uses VFP register arguments, u-boot does not

the u-boot.map shows this as source of the trouble -

/opt/armhf/gcc-linaro-arm-linux-gnueabihf-4.8-2013.09_linux/bin/../lib/gcc/arm-linux-gnueabihf/4.8.2/libgcc.a(_aeabi_uldivmod.o)

any hints to solve this?

Yes, sure, the libgcc is the one trigger it, but if I compile the uboot w/o 
JFFS2 other functions of the libgcc are linked into the u-boot loader without 
trigger the problem. libcommon , libnand + libmmmc uses udivsi3 and others

I think the root of the evil is
libgcc.a(_aeabi_uldivmod.o) (__gnu_uldivmod_helper)

I mean: use "USE_PRIVATE_LIBGCC=yes" on the make command line.

after I set this option the build failed for

/uboot.d/u-boot-git/arch/arm/lib/libgcc.o -Map u-boot.map -o u-boot
fs/jffs2/libjffs2.o: In function `jffs2_1pass_build_lists':
/opt/cross_build/uboot.d/u-boot-git/fs/jffs2/jffs2_1pass.c:1441: undefined 
reference to `__aeabi_uldivmod'

I mentioned this reference as "root of the evil" before :-)

just to let you know, I open a thread on the linaro tool-chain mail list
for this problem.
