[Qemu-devel] [PATCH v1 08/29] target-microblaze: Remove USE_MMU PVR chec


From: Edgar E. Iglesias
Subject: [Qemu-devel] [PATCH v1 08/29] target-microblaze: Remove USE_MMU PVR checks
Date: Thu, 3 May 2018 11:19:01 +0200

From: "Edgar E. Iglesias" <address@hidden>

We already have a CPU property to control if a core has
an MMU or not. Remove USE_MMU PVR checks in favor of
looking at the property.
