From 6d9c1b8dbb3527258bbc473aa3a9b02c6a86c506 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Fri, 4 May 2018 18:05:50 +0100 Subject: [PATCH] hw/arm/virt: Add linux,pci-domain property This allows to pin the host controller in the Linux PCI domain space. Linux requires that property to be available consistently or not at all, in which case the domain number becomes unstable on additions/removals. Adding it here won't make a difference in practice for most setups as we only expose one controller. However, enabling Jailhouse on top may introduce another controller, and that one would like to have stable address as well. So the property is needed for the first controller as well.
