From 7d2d3956fbc1aa9a3ccdc9389b88505232764d4f Mon Sep 17 00:00:00 2001 From: Mark Grosen Date: Tue, 13 Dec 2011 09:14:15 +0200 Subject: [PATCH] remoteproc: avoid registering a virtio device if not supported Let remoteproc know when the firmware doesn't support any virtio functionality, so registering a virtio device can be avoided. This is needed for remote processors that doesn't require any virtio-based communications, but are still controlled via remoteproc.
