Are you using 64-bit division? Tegra uses the private libgcc. This
patch might help:

Yes, I'm using 64-bit.

If I start with v2016.03, and apply the following patch, I can reproduce 
this issue when building venice2 (a 32-bit Tegra build) but not 
p2371-2180 (a 64-bit Tegra build):

diff --git a/arch/arm/mach-tegra/board2.c b/arch/arm/mach-tegra/board2.c

  	debug("%s called\n", __func__);

However, if I apply the patch Simon mentioned above, the problem is 
fixed. Are you sure you applied that patch correctly?

Perhaps you could share the local patches that are triggering the problem?

I can reproduce this when building venice2 in u-boot-spi/spi-nor-test, 
and indeed the patch that Simon linked to doesn't help. That's because 
Simon's patch implements __aeabi_uldivmod whereas the linker failure is 
due to __aeabi_ldivmod (without the u).

Simon, is it easy for you to bring in __aeabi_ldivmod from the same place?

FWIW, I hacked _uldivmod.S to provide a dummy symbol for __aeabi_ldivmod 
and the link succeeded, so I think that's currently the only missing 
symbol. I only tested the venice2 build though.

Not that I can see, sorry.

I suppose it is possible to fix up the sign but I don't have code to do it.
