Mauro Carvalho Chehab dc7a12bdfc docs: arm: convert docs to ReST and rename to *.rst
Converts ARM the text files to ReST, preparing them to be an
architecture book.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Icenowy Zheng 16fa9629c4 ARM: sunxi: add support for H2+ SoC
Allwinner H2+ is a quad-core Cortex-A7 SoC.

It is very like H3, that they share the same SoC ID (0x1680), and H3
memory maps as well as drivers works well on the SoC.

Linus Torvalds 66f2c6d952 ARM: SoC platform updates for v4.9
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - We get support for running in big-endian mode on two platforms:
   sunxi (Allwinner) and s3c24xx (old Samsung).
 
 - The recently added Uniphier platform now uses standard PSCI
   methods for SMP booting and we remove support for old bootloader
   versions that did not support it yet.
 
 - In sunxi, we gain support for the "Nextthing GR8" SoC, which
   is a close relative of the Allwinner A13 and R8 chips.
 
 - PXA completes its move over to the generic dmaengine framework
   and removes its old private API
 
 - mach-bcm gains support for BCM47189/BCM53573, their first ARM
   SoC with integrated 802.11ac wireless networking.

Maxime Ripard c1efda1238 ARM: sunxi: Support the Nextthing GR8
The GR8 is an SoC made by Nextthing Co, loosely based on the sun5i family.

It has a number of new controllers compared to the A10s and A13 (SPDIF, I2S),
but some controllers missing too (Ethernet, less I2C, less UARTs).

Maxime Ripard bef6229f36 ARM: sunxi: Add R8 support
The R8 is a new Allwinner SoC based on the A13. While both are very
similar, there's still a few differences. Introduce a new compatible to
deal with them.

In order to have a consistent naming, instead of mentioning the Allwinner
A series as the machine name, switch to sun4i/sun5i like what is done for
the other families.

So far the A31s is 100% compatible with the A31, still lets do the same
as what we've done for the A13 / A10s and give it its own compatible string,
in case we need to differentiate later.
