For now only the Quad 1GB variant is supported.
Tested:
- starting barebox over USB
- writing barebox to NAND with barebox_update
- starting Linux kernel over TFTP

This driver is based on mach-at91/gpio.c and linux pinctrl driver.
The driver contains the gpio and pinctrl parts (like in linux) because the two parts
share some structures and logics.

Otherwise building produces these warnings:
[...]

And bootm fails for x86_64. The implicit declaration has an int as return

By retrieving the ecc_mode from pdata we can use the same code for device tree and
non device tree probing. Which was not possible before, because ecc_mode was arbitrarily set to
NAND_ECC_SOFT.

dts/ is for upstream dts files only. Move barebox specific file
to arch/arm/dts/ so that it doesn't get removed by the next

As of 3.17-rc1 the upstream dts sources for the rockchip rk3188 use
incompatible clock bindings. We currently do not have the resources
to update the clock driver to this new binding, so we use local copies
of the Linux 3.16 dtsi files. Due to the incompatible change the
internal device tree won't work with kernels newer than 3.17-rc1.

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

To build an object file from a device tree currently we currently
have to add them to the Makefile twice, once to dtb-y and once to
obj-y. This patch introduces obj-dtb-y and pbl-dtb-y to directly
compile a device tree object file for inclusion in the barebox binary
or the pbl respectively.
The now unneeded dtb-y targets are removed.

We have our file helper functions in several places. Move them
all to lib/libfile.c.
With this we no longer have file helpers in fs/fs.c which contains
the core fs functions and no functions in lib/libbb.c which are
not from busybox.
