From 9ac6da9d0e0b9f7678752ff7b9c91e39c140b4e7 Mon Sep 17 00:00:00 2001 From: Peter Seebach Date: Mon, 16 Jul 2012 11:58:39 -0500 Subject: tune-ppc476.inc: Support ppc476 A couple of boards use chips which perform noticably better when optimized for the 476. Add a trivial tune file to let them run better.
