From 2b84a3640ffdebbbea3ec004eae963e920c16e1a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Thu, 4 Feb 2010 14:11:02 +0100 Subject: [PATCH] arm/mx2: use cpp magic to create imx_gpt devices MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This makes the source shorter and easier to verify. While at it switch to use the SoC-prefixed constants.
