commands: Add dhrystone ...

This tool will help to measure the system performance.

Some SoCs haven't the possibility to route their clocks to the output pins.
So you can use dhrystone to get a feedback about the clock speed.

net: dhcp: Split dhcp funcionality & add dhcp command ...

dhcp/bootp was bound to the command functionality.
This patch splits the dhcp command.
We are now able to use bootp without a shell.

This patch adds also a check for environment variables and globalvar.
So only when ENVIRONMENT_VARIABLES and GLOBALVAR is set, all received
dhcp data will be stored.

state: add framework for persistent state handling ...

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.

For more information see:
    Documentation/devicetree/bindings/barebox/barebox,state.rst

Add support for non volatile variables ...

This adds (back) support for non volatile variables. Non volatile
variables are variables which are stored in the environment over
reboot. They are used in the same way as the global variables, but
with a 'nv' command and device. The variables are stored under
/env/nv/, one variable per file. Adding a nv variable automatically
adds a global variable with the same name. Changing a nv variable
also changes the same global variable, but not the other way round.
This allows for example to configure the username as:

nv user=sha; saveenv

Introduce message logging support ...

This adds a buffer for log messages and a 'dmesg' command to
print the messages. The log buffer is implemented as log objects
rather than a string buffer. This makes it easy to implement
limiting the messages, cleaning the buffer and timestamping
the messages.

Add a Firmware programming framework ...

This framework handles a list of registered Firmware programming handlers
to unify a firmware programming interface by hiding the details how
to program a specific Firmware in its handler. This is created with FPGAs
in mind but should be usable for other devices aswell.
A user has two possibilities to load a firmware. A device file is create
under /dev/ which can be used to copy a firmware to. Additionally a
firmwareload command is introduced which can list the registered firmware
handlers and also to upload a firmware.

Add support for metadata in barebox images ...

It's often useful to get some information about a barebox image
before starting or flashing it. This patch introduces barebox
Image MetaData (IMD). When enabled a barebox image will contain
a list of tags containing the desired information. We have tags
for:

- the barebox release (2014.07.0-00160-g035de50-dirty)
- the build timestamp (#741 Mon Jul 28 15:08:54 CEST 2014)
- the board model the image is intended for
- the device tree toplevel compatible property

Also there is an additional generic key-value store which stores
parameters for which no dedicated tag exists. In this patch it
is used for the memory size an image supports.

Since there is no fixed offset in a barebox image which can be
used for storing the information, the metadata is stored somewhere
in the image and found by iterating over the image. This works
for most image types, but obviously not for SoC images which are
encoded or encrypted in some way.

There is a 'imd' tool compiled from the same sources for barebox,
for the compile host and for the target, so the metadata information
is available whereever needed.

For device tree boards the model and of_compatible tags are automatically
generated.

Example output of the imd tool for a Phytec phyFLEX image:

build: #889 Wed Jul 30 16:08:54 CEST 2014
release: 2014.07.0-00167-g6b2070d-dirty
parameter: memsize=1024

add menutree command ...

Creating menus from the shell using the regular 'menu' command is rather
complicated. This adds a 'menutree' command which creates a menu from
a directory structure. In the directory structure each directory corresponds
to a single menu entry. The directory contains the following files:

title -  A file containing the title of the entry as shown in the menu
box -    If present, the entry is a 'bool' entry. The file contains a variable
         name from which the current state of the bool is taken from and saved
         to.
action - if present this file contains a shell script which is executed when
         when the entry is selected.

If neither 'box' or 'action' are present this entry is considered a submenu
containing more entries.
