From 440f6ffc061a84e81386a093c07af8a429c18702 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Sat, 24 Dec 2011 14:36:27 +1000 Subject: m68knommu: move old ColdFire timers init from CPU init to timers code The original ColdFire timer interrupt setup is used by most of the users of the original ColdFire timer code. But the code is currently duplicated in each of the ColdFire CPU specific init files. Move it to the timers code that it is really part of. It is strait forward to make it conditional on also having the original interrupt engine that it needs.
