From 93ce3b3a28dc0aad0bb501072bc7fc31e9cd6ce2 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Fri, 24 May 2013 14:38:48 -0700 Subject: ARMv7: flatten arch/armv7 source tree With only 19 source files it doesn't make a whole lot of sense to create sub directories in arch/armv7, especially since the files were distributed somewhat randomly.
