[PATCH 0/4] CPU hotplug support for Versatile platforms

[Will Deacon]

This patch series fixes some issues with the RealView CPU hotplug code and then
factors out the common code into plat-versatile. Finally, support for multiple
tiles is added to the Versatile Express BSP in order to decouple the
tile-specific functions from the motherboard and hotplug support is
added to the ct-ca9x4 tile using the new platform code.

Taken against 2.6.35 and tested on RealView PB11MPCore and Versatile Express
[ct-ca9x4] boards.
