From 2a45addd21de25f41c8f21a6f08f0980e583d596 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Fri, 12 Jan 2018 13:45:19 +0100 Subject: powerpc/8xx: Remove CPU6 ERRATA Workaround CPU6 ERRATA affects only MPC860 revisions prior to C.0. Manufacturing of those revisiosn was stopped in 1999-2000. Therefore, it has been almost 20 years since this ERRATA has been fixed in the silicon. This patch removes the workaround for that ERRATA.
