I tried:

pavel at amd:~/mainline-altera/u-boot$ LANG=C
CROSS_COMPILE=arm-linux-gnueabi- ./MAKEALL socfpga_cyclone5
Configuring for socfpga_cyclone5 board...

Guilty as charged. We did not want to specify type of stack and malloc
pools. Patch below should fix it.

But this one is a mystery. Offending lines are:

#include <netdev.h>

DECLARE_GLOBAL_DATA_PTR;

[line 26:] void show_boot_progress(int progress)
{
        debug("Boot reached stage %d\n", progress);
}

Do we need direct include asm/global_data.h for
DECLARE_GLOBAL_DATA_PTR? Is something funny going on with debug()? Is
show_boot_progress() a macro in your build? Would it be enough to
check out current u-boot-arm to reproduce?

Thanks,
