[coreboot] r786 - in coreboot-v3: arch/x86 include lib

Author: hailfinger
Date: 2008-08-18 22:13:11 +0200 (Mon, 18 Aug 2008)
New Revision: 786

Modified:
   coreboot-v3/arch/x86/stage1.c
   coreboot-v3/include/console.h
   coreboot-v3/lib/console.c
Log:
Move console log level management to global variable infrastructure. The
existing code does not work due to the characteristics of stage1. This
has been broken since r729.
