ARMV7: Versatile Express Coretile CortexA9x4 support
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 This gives ca9x4_ct_vxp.c as the board support file.
