[U-Boot] problem on SPL build

[Simon]

Hi,

I'am studying on u-boot, and i am trying to port it on smdkc100. I setup
cross-compile on ubuntu12.04 and build the u-boot, it works okay.
But i have a problem on SPL build.

I hope you can help me to solve it, thanks!

problem:

insert file "smdkc100.h" at Line 25
#define CONFIG_SPL
and then
make distclean
make smdkc100_config
make all
but get error:
/u-boot-2014.01/arch/arm/lib/crt0.S:74: undefined reference to
`board_init_f'
