From 092cba0350f073d465492c39210a006e5cb18f63 Mon Sep 17 00:00:00 2001 From: Jean-Philippe Brucker Date: Fri, 10 Dec 2021 17:04:10 +0000 Subject: [PATCH] hw/arm/virt: Remove device tree restriction for virtio-iommu virtio-iommu is now supported with ACPI VIOT as well as device tree. Remove the restriction that prevents from instantiating a virtio-iommu device under ACPI.
