Iglesias" Date: Fri, 13 Apr 2018 09:46:28 +0200 Subject: target-microblaze: Remove USE_MMU PVR checks 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. Reviewed-by: Alistair Francis Reviewed-by: Richard Henderson Signed-off-by: Edgar E.
