Current barebox,environment node only allows specifying a raw device or
partition to load an environment from. Some boards, like OMAP and
SoCFPGA, instead want to use a file located in a FAT filesystem.
Extend the device tree bindings with a new property 'file-path' that
will trigger this behavior.
This allows any board using this driver to get the env from a file or
from a raw device, instead of each machine type being either raw
device only or file only.

This patch adds hmac support to the raw backend.
With this patch, modifications of the header or data of a state partition can
be detected, as the hmac woudln't match anymore. The hmac relies on a shared
secret, which is requested from the keystore, with keystore_get_secret() using
the name of the state partition as the "name" of the secret.

We could only point to partitions in the device tree by using
&norflash, "partname:barebox-environment". Allow to point to the
partition directly without having to parse the partition labels.

Some SPI NOR flashes support 4K erase blocks. 4K erase blocks do not
work with UBIFS which needs a minimum erase block size of 15360 bytes.
Also bigger sectors are faster to erase. This patch adds a device tree
option to use the bigger blocks instead of the default 4K blocks.

It's "uint32" not "u32" and we use integers for the "enum32" defaults.

This patch adds a framework to describe, access, store and restore a set of
variables. A state variable set can be fully described in a devicetree node.
This node could be part of the regular devicetree blob or it could be an extra
devicetree solely for the state. The state variable set contains variables of
different types and a place to store the variable set.

Altera FPGAs that are programmed via SPI use the passive serial protocol.
Add a simple binding that describes the setup for this usecase.

This is a rewrite of the Documentation in reStructuredText format using
Sphinx as build system, see http://sphinx-doc.org/.
The documentation is built into static html pages with 'make docs'.
The pages can be found under Documentation/html after building.

Remove the barebox devicetree documentation. It will
be replaced with sphinx based documentation later.

This adds the possibility to configure the place for the environment
from the devicetree and to partition devices from the devicetree.
Configuration has the general form of devices with a regular compatible
property. This allows to later add additional drivers or drivers with
different behaviour (for example to add support for redundant environment).
The configuration is all in the /chosen/barebox/ hierarchy of the
devicetree. This separates the configuration from the hardware
description. Also it makes it possible to store the configuration
in a completely separate devicetree (or devicetree overlay). For
the same reason all configuration is done using nodepathes rather
than phandles.
