Subject: [PATCH v2] ARM: arm64: dts: Add expansion bus to VExpress and Juno
The VExpress and Juno development platforms have an external expansion
bus which can be used for additional hardware (e.g. LogicTile Express
daughterboards).
Add this bus to all VExpress CoreTile and Juno device-trees.
On VExpress, the bus is described for a CoreTile occupying site 1.
