The existing nand_boot functions all do the same, so move it to
a common place. To be flexible enough for future boards the real
image size is used instead of hardcoded 256k.

Depending on the SoC a barebox.bin, barebox.netx, barebox.s5p, MLO image
is generated. With pbl support there now is an additional
arch/arm/pbl/zbarebox.bin image.
To help the user to determine which image should be flashed to his device,
generate a barebox-flash-image link.

This allows for creating a pre-bootloader binary for
- nand boot
- mmc boot
- compressed image
Currently on the compressed image is implemented the boot really on current lowlevel
init support. In a second step this could be move to the pbl c code with generic framework.
The pbl will be incharge of the lowlevel init if needed.
The barebox will skip it.
The decompressor support lzo and gzip and allow to add easly more.

This allows for creating a lzo compressed binary unsing the pbl.
Only copy the piggydata if needed.
Add CONFIG_PBL_FORCE_PIGGYDATA_COPY option
In some case we need to copy the PIGGYDATA as the link address
as example we run from SRAM and shutdown the SDRAM/DDR for
reconfiguration but most of the time we just need to copy the
executable code.

Import string functions from linux 3.4 (arch/arm/boot/compressed/string.c) and
implement a dummy panic.
For now on introduce dummy zbarebox* targets and c code that will contain later
the decompressor. This only implemeted on ARM.

This will allow to link compiled object to the built-in-pbl.o across the source
tree that will be finally link to the pbl.
Now we compile the source %.c in pbl-%.o and provide -D__PBL__
so we can known in the source when it's compile for barebox or the pbl.

| mem md: bail out without arguments
|
| Without arguments the 'md' command defaults to show address 0 which
| likely results in a NULL pointer exception, so only three keystrokes
| are necessary to crash barebox. Show usage instead if 'md' is invoked
| without arguments, so that it at least requires an address to be given
| to crash barebox. This increases the stability of barebox by 66%. Hurray!
barebox does not crash any longer when a plain 'md' without additional arguments
is exectuted. However, doing a 'md -s /dev/nor0' was a standard usecase which now
does not work anymore.

The i.MX5 does not have a valid function to get the spi clock. This
patch introduces a function for i.MX6, and moves the bogus spi clock
speed to the speed-imx5*.c. Not nice, but preserves the current status
quo for i.MX5
