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.
