[coreboot] r816 - in coreboot-v3: arch/x86 northbridge/amd/k8

Author: rminnich
Date: 2008-08-24 19:47:22 +0200 (Sun, 24 Aug 2008)
New Revision: 816

Added:
   coreboot-v3/northbridge/amd/k8/libstage1.c
Modified:
   coreboot-v3/arch/x86/Makefile
Log:
add libstage1.c

Remove pcspeaker until I can resolve space issues. Nobody was using it 
anyway as it happens. It will go back in as soon as we 
1. grow stage1 or
2. reconfigure it again
