From 7fc92c6092d7208e53d35cda32a9181aae396adf Mon Sep 17 00:00:00 2001 From: Gwenhael Goavec-Merou Date: Fri, 29 Apr 2011 05:21:39 +0000 Subject: [PATCH] MX1: Add ARMadeus Systems APF9328 board support MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit APF9328 is an i.MXL based SOM (System On Module) that can be plugged on several docking/development boards. Here only basic module support is added (Ethernet, Serial, NOR Flash).
