From 029faf3e85e9406f32f133e6f2a114ed26b02fb4 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 27 Apr 2010 11:37:28 +0200 Subject: [PATCH] ppc4xx: Add support for ICON board (PPC440SPe) This patch adds support for the Mosaix Technologies, Inc. ICON board, based on the AppliedMicro (AMCC) PPC440SPe. It's equipped with an SODIMM (512MB standard) and 64MByte of NOR FLASH. Support for the onboard SM502 will be added later.
