Treewide: remove address of the Free Software Foundation ...

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

booting: more flexible Linux bootargs generation ...

We currently use the environment variable 'bootargs' to get the
Linux bootargs. This patch allows for a more flexible bootargs
generation using global variables. With it the Linux bootargs
are concatenated from multiple variables. This allows to replace
parts of the bootargs string without having to reconstruct it
completely.
With this bootargs can be constructed like:

global linux.bootargs.base="console=ttyS0,115200"
global linux.bootargs.ip="ip=dhcp"
global linux.mtdparts="physmap-flash.0:512K(nor0.barebox),-(root)"

This will then automatically be combined into a kernel bootargs
string during boot.

If the 'linux.bootargs.' variables are all empty the old standard
'bootargs' way will be used.

bootm: use new uimage code ...

This switches the bootm code to the new uimage code. Also
bootm can now handle other types of images than uImages.
Currently the only architecture making use of this is
arm which allows to boot zImages, raw images and barebox
images.
I intended to make a more bisectable series from this but
I failed becuase there are many dependencies and no matter
how I tried the patches grew bigger and and bigger. So I
decided to put this all in a single patch.

bootm: push relocate_image up to the generic command ...

All handlers used to just relocate the image without any checks, so
we are doomed if we write outside of SDRAM or will overwrite ourselves.
Move the relocation up to the generic part where we have a chance
of catching these issues.
