From 91a51fecef20ba4ee659a68a55b2b556f070908d Mon Sep 17 00:00:00 2001 From: Fabiano Rosas Date: Fri, 28 Jan 2022 13:15:07 +0100 Subject: [PATCH] target/ppc: 74xx: System Reset interrupt cleanup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The whole power saving states logic seems to be dependent on HV mode, which don't exist for 74xx so I'm removing it all and leaving the abort message.
