f01b9b73f5 arm-soc: new SoC support
This adds support for three new SoC types:
 * 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.

06b4ba5295 ARM: OMAP2+: omap2plus_defconfig: EHCI driver is not stable, disable it
The EHCI driver is not stable enough to be enabled by default.  In v3.5,
it has at least the following problems:

- warning dump during bootup
- hang during suspend
- prevents CORE powerdomain from entering retention during idle (even
  when no USB devices connected.)

This demonstrates that this driver has not been thoroughly tested and
therfore should not be enabled in the default defconfig.

In addition, the problems above cause new PM regressions which need be
addressed before this driver should be enabled in the default
defconfig.

This shrinks it down a bit more and makes it easier

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

6f911492ed omap: Update omap2plus_defconfig to use ttyO instead ttyS
With the omap-serial the device has changed from ttyS to ttyO as
the system may have both omap-serial and 8250 ports.

Note that systems using omap-serial need to be updated to use ttyO[012]
instead of ttyS[012] in the bootloader, CONFIG_CMDLINE, /etc/inittab,
and the root file system with mknod. Also you may need to add ttyO[012]
to /etc/securetty.

455d4d2dc7 omap: Update and rename common defconfig for omap2plus devices
This patch addresses below things

- Renaming existing omap3_defconfig which has OMAP2, OMAP3 and OMAP4 builds
  enabled to more appropriate name 'omap2plus_defconfig'
- L1 cache shift is suppose to be 5 on OMAP4 where as it is 6 on previous
  OMAPs. Keeping it to 5 is safer option for OMAP4 and previous OMAPs. For
  OMAP3 only build the shift would be still 6
- Enable needed Errata's for OMAP4 to work with DMA based device drivers
	CONFIG_PL310_ERRATA_588369=y
	CONFIG_ARM_ERRATA_720789=y
- Enable the Micrel ethernet controller
	CONFIG_KS8851=y
	CONFIG_KS8851_MLL=y

With above three changes, OMAP4 ethernet, mmc etc works reliably.
