From 22b8c9f5baeb440a716ea760ff05290221565b4c Mon Sep 17 00:00:00 2001 From: David Erb Date: Tue, 24 Oct 2006 18:31:20 +0200 Subject: [POWERPC] cell: update Cell BE register definitions There are a few definitions that are required by subsequent patches, so add them here. The original patch is from David Erb, but is significantly cleaned up by Kevon Corry.
