From 799fed98ea57fc9632b7bf95b3f1d79519cbdd15 Mon Sep 17 00:00:00 2001 From: Kerry She 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.
