From a501d8f30e4fcca563e4ee462be00f96e51181d5 Mon Sep 17 00:00:00 2001 From: Martin Langer Date: Sun, 7 Sep 2008 17:51:32 +1000 Subject: [PATCH] powerpc: Fix major revision number for Freescale cores Some 74xx cores by Freescale are using the configuration field instead of the major revision field for their revision number. This corrects the wrong behaviour for those ppc cores including my one. There is a reference document at Freecale. It describes the PVR register. This is based on that pdf.
