Subject: qgraph: allow extra_device_opts on contains nodes
X-Git-Tag: v4.1.0-rc0~77^2~15
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=de94b54aa04c06f5988221d2d7e6ee3469173c4b;p=thirdparty%2Fqemu.git

qgraph: allow extra_device_opts on contains nodes

Allow choosing the bus that the device will be placed on, in case
the machine has more than one.  Otherwise, the bus may not match
the base address of the controller we attach it to.
