ARM: bootm: Print Kernel commandline unconditionally ...

The Kernel commandline is an important debugging aid when people
ask why their Kernel won't start, so print it unconditionally.
This is done in !dt mode anyway, so also do it with dt.

bootm: Pass unflattened devicetree to handlers ...

This makes it possible to modify the tree in the handlers.
This is necessary because the initrd addresses are only
known inside the handlers, but not to the generic bootm
code.

ARM: bootm: rework concatenated oftree ...

Without compiled in devicetree support we used to copy the
concatenated devicetree directly behind the zImage. This is
unnecessary, even if we do not have devicetree support we can
copy the devicetree whereever we like and pass the kernel a
pointer to it. This makes the code a bit easier.
While at it, add the missing free calls in the error case.

filetype: Pass bufsize ...

Pass the buffer size to the file detection code. This makes sure we do not
read past the buffer. This is especially useful for ext filesystem detection
as the magic is at byte offset 1080. Also introduce a FILE_TYPE_SAFE_BUFSIZE
define which is set to the minimum bufsize the detection code needs to detect
all known filetypes.

resource: store 'end' instead of 'size' in struct resource ...

Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.

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.

arm: add Android boot image support ...

The Android Image contains 3 components and params

 - kernel
 - initrd
 - second stage (optional)

 - tags addr
 - bootargs

In fast boot the initrd is mandatory, in barebox we are less restrictive
use the initrd only if present

add to env params:
aimage_noverwrite_bootargs
	Disable overwrite of the bootargs with the one present in aimage

aimage_noverwrite_tags
	Disable overwrite of the tags addr with the one present in aimage

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.
