From d109167b9c1002770d194644d5580a1f3588f7fc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Thu, 10 Jun 2010 15:11:13 +0200 Subject: ARM: imx: rename mach dir for mx21 and mx27 to mach-imx MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Finally all imx code should end up there, start with mach-mx2. While touching all files rename some files to use a hyphen instead of an underscore.
