From b0022ab871d3590f2d074ad1359a4cd0627a2741 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Sat, 28 Feb 2015 20:34:06 +0000 Subject: [PATCH] Ovfm/Xen: add a Vendor Hardware device path GUID for the XenBus root On non-PCI Xen guests (such as ARM), the XenBus root is not a PCI device but an abstract 'platform' device. Add a dedicated Vendor Hardware device path GUID to identify this node.
