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
of_compatible: phytec,imx6x-pbab01 phytec,imx6dl-pfla02 fsl,imx6dl
model: Phytec phyFLEX-i.MX6 Duallite Carrier-Board

read_file: introduce read_file_2 ...

read_file has some limitations:

- It is not possible to check the error code since read_file returns
  NULL for failure
- It is not possible to limit the buffer size to sensible limits.

This patch introduces read_file_2 which doesn't have these limitations.
read_file becomes a wrapper around read_file_2.

envfs: change API to be able to forward special flags into the envfs superblock ...

In order to be able to mark an stored envfs image with special features
(intentional ignore for example), we now can feed forward these flags.
By forwarding a '0' for the flags nothing changes because the envfs superblock
was already allocated with xzalloc.

envfs: provide an intentional way to ignore an existing external environment ...

Add a simple flag to envfs to be able to mark an external environment as

This change should not affect existing systems, because the current envfs

zeroed.

net: phy: Add minimal support for QSGMII PHY ...

Based on Linux's support by Thomas Petazzoni:

    commit b9d1208
    Author: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
    Date:   Tue Apr 15 15:50:19 2014 +0200
    net: phy: add minimal support for QSGMII PHY

    This commit adds the necessary definitions for the PHY layer to
    recognize "qsgmii" as a valid PHY interface. A QSMII interface, as
    defined at
    http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface,
    is "is a method of combining four SGMII lines into a 5Gbit/s
    interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX
    data and a single LVDS clock signal. QSGMII uses significantly fewer
    signal lines than four SGMII busses."

    This type of MAC <-> PHY connection might require special handling on
    the MAC driver side, so it should be possible to express this type of
    MAC <-> PHY connection, for example in the Device Tree.

pci: set auto-incremented bus number ...

When using more than one PCI bus, we have to assign unique numbers
to each bus. Use an auto-incremented bus index and assign it to
each registered bus. Also, allow the PCI host controller to update
internal registers by calling set_busno with assigned bus number.

While at it, add pci_controller struct to set_busno callback,
add a back reference to pci_controller to pci_bus, and clean up
unused left-overs from Linux import.

ARM: mvebu: allow to fixup mbus ranges ...

On Marvell MVEBU SoCs internal registers are usually remapped from reset
default. While Dove and Kirkwood always had their registers remapped,
some Armada 370 and XP where shipped with bootloaders that did not remap
them.

On Barebox these registers are remapped early and on all MVEBU SoCs, so
provided DTs should always reflect that in their mbus ranges property.

This patch registers a fixup for DTBs and allows individual SoCs to add
specific remap ranges to the fixup list. The fixup is registered on
pure_initcall to even allow to fixup pbl or appended DTBs.
