From: Greg Ungerer Date: Thu, 8 Dec 2011 05:39:05 +0000 (+1000) Subject: m68k: consolidate the vmlinux.lds linker scripts X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=40c1b9cfeedf79b909c961e0e00a13497e80bc82;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git 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.
