Subject: [PATCH v4 20/27] xen/arm: Remove devices used by Xen from dom0 device tree
Date: Fri, 13 Sep 2013 13:49:27 +0100 [thread overview]
Message-ID: <1379076574-28316-21-git-send-email-julien.grall@linaro.org> (raw)
In-Reply-To: <1379076574-28316-1-git-send-email-julien.grall@linaro.org>
Devices used by Xen should not be pass-through to dom0. If the device is really
usefull for dom0 (for instance the timer and the GIC), it will recreate the
node.
