Subject: [PATCH] [PATCH] create common vector setup code for
 m68knommu/ColdFire

This patch creates a common set of vector code for the ColdFire
sub-architecture of the m68knommu architecture. The basic setup
code for all ColdFire CPU's is the same. Some more patches will
follow this that remove theis common code from each of the
ColdFire CPU configs.
