New Revision: 1084

Modified:
   coreboot-v3/arch/x86/intel/core2/stage1.c
Log:
This is an emergency fix for the kontron. This fix now allows us to boot to 
etherboot. 

The fix is to replace the wbinvd with an invd. The wbinvd is a bad idea, 
since the cache at this point is full of tags to a location that is not backed 
by memory.
