This allows for creating a pre-bootloader binary for
- nand boot
- mmc boot
- compressed image
The pbl will be incharge of the lowlevel init if needed.
The barebox will skip it.
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.

The generic A9M2440 comes in many SDRAM variantes. Two GPIO pins describing
the populated SDRAM devices. This patch adds some code to query the setting
and setup a correct SDRAM configuration out of four possible variants.
Due to the lack of hardware the 16 MiB and 128 MiB case is untested yet.
Due to the 32 MiB configuration we must link the u-boot-v2 always to
address 0x31fc0000. Even for the 64 MiB and 128 MiB configuration.

We used to initialize the PLLs on PCM038 in two
steps. The first was to initialize a basic setup
so that all peripheral clocks run at their final
speed and the second step was to push the processor
to full speed after the PMIC has been initialized
for the higher voltage.
Do this in one step instead to get an easier setup.

values into kconfig which are not user configurable at all only
encourages people to put even more stuff in there. This is not
good because people tend to have board patches lying around and
these patches won't apply regularly if they all change the same
file (arch/arm/Kconfig)
Instead, introduce a function armlinux_set_architecture() which
everyone can call during board setup.
Similarly introduce armlinux_set_bootparams() for the boot
parameter pointer.
a generic linker script to arch/arm/lib/u-boot.lds.S.
If a board wants to overwrite a linker script it can do
so using CONFIG_BOARD_LINKER_SCRIPT.
There is no generic linker script for ppc and blackfin
yet, so still use the board specific one.
This patch makes TEXT_BASE a consistent per-arch config switch.
Additionally, it converts all TEXT_BASE occurences from string to hex.
