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.
