sr at denx.de
Tue Apr 27 11:37:28 CEST 2010
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.
Signed-off-by: Stefan Roese <sr at denx.de>

v2:
- Updated to compile with new arch/powerpc directory structure
- Minor changes to the commit text
