Date: Thu, 14 Apr 2016 16:39:18 +0100 [thread overview]
Message-ID: <1460648359-7310-1-git-send-email-brian.starkey@arm.com> (raw)
The VExpress development platform has an external expansion bus which
can be used for additional hardware (e.g. LogicTile Express
daughterboards).
Add this bus to the VExpress CoreTile device-trees.
The bus is described for a CoreTile occupying site 1.
