Hi All,

I'm currently porting our u-boot implementation that is about 2 years old to the current git repository, and I've hit a snag during linking.

It can't find my 'board_nand_init' function. It defined in my nand.c and it is being compiled. So what could I have missed in reconfiguring my board?

I'm getting this error:

How big is your nand.o? Do you have an ifdef in the file which is not defined and perhaps preventing the code from being compiled?
