All the smcs family chips 91c94, 91c96, 91c100, 91c111 share almost the
same behavior and register sets. The noticeable exceptions are coped
with in this patch, ie :
- 91c94 and 91c96 only have an internal 10 Mbps phy
The registers used for phy discovery on later chips will corrupt the
91c96 state.
- 91c94 and 91c96 have a control and config register quite different
from their 91c1xx conterparts
A platform data user defined couple of registers is introduced. If
these values are 0, 91c1xx legacy behavior is assumed.

Smc network IPs can be wired up in different funny ways. For example the
lubbock pxa25x development platform wires all address lines shifted by
2, ie. bus A2 is smc91c96 A0, bus A3 is smc91c96 A1 etc ...
In order to cope with the different possible combination, add a shift
parameter for addresses.

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

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.

For situations when we don't know the desired mode for the OTG port
we register a otg device which has a mode parameter to specifiy the
desired mode on the command line.

We have USB_SPEED_* definitions as macros in usb_defs.h and as an enum
in ch9.h. The defines in usb.h correspond to hardware bits in the
ehci controller. Get rid of them and keep the hardware independent
enums.

Currently we have two conflicting definitions of struct usb_config_descriptor
and struct usb_interface_descriptor in the tree. This is because the USB code
uses additional fields in the structs for internal housekeeping. Add
struct usb_interface and struct struct usb_configuration with the housekeeping
data and embed the corresponding hardware structs into them. This frees the
way to use the definitions from ch9.h in the next step.

Yes, we already have roundup/rounddown. Unlike these macros
round_up/round_down are optimized to (and only work with)
power-of-2 arguments. It's a poor name, but kernel code needs
it, so add it to barebox aswell.

During debugging it sometimes helps to me even more verbose. This
adds an additional debug level for this. Also we remove an already
existing pr_vdebug definition in the USB gadget u_serial driver.
