Everyone,

I tried to port I946GZ and following from 945 example on intel mainboard,

and I got error when compiling :

build/romstage/mainboard/intel/i946gz/romstage.o: In function

src/arch/x86/Makefile.inc:264: recipe for target

When I patch it with :

#include <southbridge/intel/i82801gx/early_lpc.c>
#include <southbridge/intel/i82801gx/early_smbus.c>
#include <southbridge/intel/i82801gx/lpc.c>

the errors are gone but I got :
