Adds support for the ARM quad-core Cortex-A9 processor. This system includes a motherboard(Versatile Express), daughterboard(Coretile), and SOC(Cortex-A9 quad core). The serial port, ethernet, and flash systems work with these additions. The naming convention is:

SOC -> CortexA9 quad core = ca9x4 daughterboard -> Coretile = ct motherboard -> Versatile Express = vxp

So ca9x4_ct_vxp.c is the board support file.
