ARM: Multi PBL: Fix image calculation for certain toolchains
...
The current way to calculate the compressed image position works
with the OSELAS toolchains, but not with the Debian/Ubuntu toolchains.
For these toolchains &image_end_marker already returns the correct
address, adding global_variable_offset() to it is wrong.
The solution seems to be to put the image_end_marker into a different
object file so that the compiler cannot play any tricks to resolve
the address internally in the object file.

Fix output format for aarch64. Also, relocation fixup symbols are in
rela section rather than rel section.

ARM: move away from ld_var
...
The ld_var solves the issue that when compiled with -pie the linker
provided variables are all 0x0. This mechanism however refuses to
compile with aarch64 support.
This patch replaces the ld_var mechanism with a nice little trick
learned from U-Boot: Instead of using linker provided variables
directly with "__bss_start = ." we put a zero size array into
a separate section and use the address of that array instead of
the linker variable. This properly works before relocation.

ARM: scroll past image end without ld_var
...
ld_var is going to be removed, cope without it. In the PBL image
we want to get the location after the binary to the place where
the compressed image is located. To do this Put a variable at
the very end of the binary, get it's location and add an offset.

sizes.h: move include/sizes.h to include/linux/sizes.h
...
This file originates in Linux. Linux has it under include/linux/
directory since commit dccd2304cc90.
Let's move it to the same place as well in barebox.
This commit was generated by the following commands:
find -name '*.[chS]' | xargs sed -i -e 's:<sizes.h>:<linux/sizes.h>:'
git mv include/sizes.h include/linux/

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

treewide: remove address of the Free Software Foundation

The FSF address has changed; The FSF site says that
address is
Free Software Foundation
51 Franklin Street, Fifth Floor
Boston, MA 02110-1301
USA
(see http://www.fsf.org/about/contact/)
Instead of updating it each time the address changes,
just drop it completely treewide.

Load PBL into SRAM
...
This allows to load all the lowlevel init code, including the
uncompressor, inside SRAM and not just the bare init part. This is
useful when pbl is used as a first-stage bootloader but is loaded by an
external firmware.

ARM: Add image end section
...
In the upcoming multi image build process we will cat images together.
To find the concatenated image we need to reliably find the end of the
current binary. This adds a dummy section at the end of a pbl binary.
Its only purpose is to mark the end of the image. The multi image
patches will add something to this section so that it doesn't get
discarded by the linker.

ARM: pbl: move linker script to lib
...
Since the pbl linker script can be reused by the upcoming multi image
build process move it to a common place. Also remove ENTRY() from the
linker script and instead add the -e option to the linker. This makes
the entrypoint configurable.
