From 799fed98ea57fc9632b7bf95b3f1d79519cbdd15 Mon Sep 17 00:00:00 2001
From: Kerry She <Kerry.she@amd.com>
Date: Sat, 1 Jan 2011 17:44:07 +0000
Subject: Add AMD SB800 southbridge CIMx code.

The main CIMx code is in a src/vendorcode directory and should not be
changed with regard to coding style etc. in order to remain easily syncable
with the "upstream" AMD code.

Signed-off-by: Kerry She <Kerry.she@amd.com>
Acked-by: Stefan Reinauer <stepan@coreboot.org>
