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

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.

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

If an external environment storage should be used in very rare and special cases,
the intentional behaviour should be to ignore the external environment and always
fall back to the built-in environment. By storing an empty "to be ignored" environment
into the external environment a confusing error message about invalid CRC sums will go
away and still the built-in environment is used.
With this new option we can force the intentional behaviour.

These variables are used to configure the USB vendor id, product id,
manufacturer name and product name.
Previously these were configured with arguments to the usbserial
and dfu command. The parameters are device static, so it's nice to
configure it somewhere in the environment instead of when calling
dfu/usbserial. Also when other gadget drivers are added we do not
have to duplicate the option parsing further.

Suppose you have two network controllers.
The first one is ENC28J60 (it is in low power mode
after start) the second one is always-enabled eth1.
As ENC28J60 is in low power mode before enc28j60_eth_open()
is called. ENC28J60's mii traceiver is in low power mode too
so the mii traceiver's register are inaccessable.
Here is a sample log just after barebox start:
barebox:/ miitool
miibus0: registered phy as /dev/phy0
No MII transceiver present!.
miibus1: registered phy as /dev/phy1
phy1: eth1: negotiated 100baseTx-FD, link ok
barebox:/ miitool
No MII transceiver present!.
phy1: eth1: negotiated 100baseTx-FD, link ok
The 'No MII transceiver present!.' message is confusing here.
This patch fixes the problem so the miitool output
looks like this:
