Pull support for three new arm SoC types from Arnd Bergmann:

 - The mvebu platform includes Marvell's Armada XP and Armada 370 chips,
   made by the mvebu business unit inside of Marvell.  Since the same
   group also made the older but similar platforms we call "orion5x",
   "kirkwood", "mv78xx0" and "dove", we plan to move all of them into
   the mach-mvebu directory in the future.

 - socfpga is Altera's platform based on Cortex-A9 cores and a lot of
   FPGA space.  This is similar to the Xilinx zynq platform we already
   support.  The code is particularly clean, which is helped by the fact
   that the hardware doesn't do much besides the parts that are expected
   to get added in the FPGA.

 - The OMAP subarchitecture gains support for the latest generation, the
   OMAP5 based on the new Cortex-A15 core.  Support is rather
   rudimentary for now, but will be extended in the future.
