This patch adds support for Versatile express FVP (Fast models). Versatile express is a family of platforms that are based on ARM v7. Currently this port has only been tested on Cortex A7, although it should work with other ARM V7 cores that support LPAE, generic timers, VFP and hardware divide. Future patches will support other cores like Cortex A5 that dont support features like LPAE and hardware divide. This platform is tested on and only expected to work on single core models.
