New Revision: 2772

Added:
   trunk/LinuxBIOSv2/src/arch/i386/lib/failover.c
Modified:
   trunk/LinuxBIOSv2/src/mainboard/msi/ms6178/Config.lb
Log:
Add a common/global failover.c file which can be used by all
(or at least most) mainboards. This should put and end to
copy-paste'ing the same file again and again for every mainboard.

Fix the build for the MSI MS-6178 target (wrong location of the common
failover.c file).
