The current Versatile Express BSP defines the MACHINE_START macro in the core tile code. This patch moves this into the generic board code and introduces a method for determining the current tile at runtime, allowing the Kernel to have support for multiple tiles compiled in. Tile-specific functions are executed via a descriptor struct containing the correct implementations for the current tile.
