Log:
Index: northbridge/intel/i945/stage1.c
Make statics non-static (we don't do buildrom any more)
Index: northbridge/intel/i945/raminit.c
remove snarf-o that left k8 in (I used wrong script I guess?)
Index: southbridge/intel/i82801gx/libsmbus.c
Corrections (minor)
Index: southbridge/intel/i82801gx/stage1_smbus.c
static to global
Index: mainboard/kontron/986lcd-m/stage1_debug.c
don't include statictree.c
Index: mainboard/kontron/986lcd-m/stage1.c
Remove functions that have to be in initram.
Index: mainboard/kontron/986lcd-m/initram.c
Add functions. This is all about splitting auto.c into stage1 and initram.
stage1 is very small and limited.
