From ab9367e38fa97c2ed7f72fd5fa29d0d70d58df89 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 12 Feb 2007 11:29:04 +0100 Subject: [PATCH] [POWERPC] ppc: Add support for AMCC Taishan 440GX eval board This patch adds support for the AMCC Taishan PPC440GX evaluation board. This is still an arch/ppc port. I'm aware that the move of 4xx to arch/powerpc is making good progress right now. So this patch is mainly intended to make the Taishan support available for the community right now.
