From 7c9e89bd1f62ccd76eee8ad4c36185057576dd95 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 7 Feb 2013 01:48:30 +0000 Subject: ppc: Remove PCIPPC2 and PCIPPC6 boards These boards seem to be unmaintained for quite some time. So lets remove support for them completely. This also cleans up some common drivers/files.
