From 40c1b9cfeedf79b909c961e0e00a13497e80bc82 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Thu, 8 Dec 2011 15:39:05 +1000 Subject: m68k: consolidate the vmlinux.lds linker scripts The merge of m68knommu left the linker scripts a little disorganized. Some consistent naming and squashing two of scripts that just include others can simplify things a lot. So merge the two simple including scripts, and rename the nommu script to be consistent with the existing m68k linker scripts.

The image layout is correct for loading on existing ColdFire dev boards. The only addition required to the current non-MMU linker script is to add support for the fixup section.
