From a9838cf7961746801a6d50cf524a62575fe3c092 Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Thu, 13 Sep 2007 08:38:24 +0000 Subject: 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).
