From 2ec11f2320f6146321574c73b9cd6196f861eb10 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Tue, 19 Nov 2019 15:12:10 +0100 Subject: [PATCH] aspeed: Change the "scu" property definition MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Aspeed Watchdog and Timer models have a link pointing to the SCU controller model of the machine. Change the "scu" property definition so that it explicitly sets the pointer. The property isn't optional : not being able to set the link is a bug and QEMU should rather abort than exit in this case.
