[PATCH 6/6] sabre: don't call sysbus_mmio_map() in sabre_realize()


From: Mark Cave-Ayland
Subject: [PATCH 6/6] sabre: don't call sysbus_mmio_map() in sabre_realize()
Date: Sun, 20 Sep 2020 09:20:18 +0100

The device should not map itself but instead should be mapped to sysbus by the
sun4u machine.
