Merge branch 'sti/soc' into next/late 

From Srinivas Kandagatla <srinivas.kandagatla@st.com>:

This patch-set adds basic support for STMicroelectronics STi series SOCs
which includes STiH415 and STiH416 with B2000 and B2020 board support.

STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for
use in Set-top-boxes. The SOC support is available in mach-sti which
contains support code for STiH415, STiH416 SOCs including the generic
board support.

The reason for adding two SOCs at this patch set is to show that no new
C code is required for second SOC(STiH416) support.

* sti/soc:
  ARM: stih41x: Add B2020 board support
  ARM: stih41x: Add B2000 board support
  ARM: sti: Add DEBUG_LL console support
  ARM: sti: Add STiH416 SOC support
  ARM: sti: Add STiH415 SOC support

STi ARM Linux Overview
==========================
Introduction
------------
The ST Microelectronics Multimedia and Application Processors range of
CortexA9 System-on-Chip are supported by the 'STi' platform of
ARM Linux. Currently STiH415, STiH416 SOCs are supported with both
B2000 and B2020 Reference boards.
configuration
-------------
A generic configuration is provided for both STiH415/416, and can be used as the
default by
make stih41x_defconfig
Layout
------
All the files for multiple machine families (STiH415, STiH416, and STiG125)
are located in the platform code contained in arch/arm/mach-sti
There is a generic board board-dt.c in the mach folder which support
Flattened Device Tree, which means, It works with any compatible board with
Device Trees.
