Add basic support for the Xilinx Zynq-7000 EPP architecture.
The Zynq-7000 is an embedded processing platform that combines a Cortex A9
dualcore MPSoC with an Artix-7 FPGA.

Add rules to generate dtb files from dts/dtsi files,
optionally run the source files through the preprocessor.
Also add a rule to generate object files to include in
the barbox binary.

Defining STACK_BASE and MALLOC_BASE only makes sense when
either CONFIG_MEMORY_LAYOUT_DEFAULT or CONFIG_MEMORY_LAYOUT_FIXED
is set, so use separate #ifdefs instead ot #if/#else

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.

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 ep93xx needs a special value at offset 0x1000. Rather than
do special handling in the linker file add aa header section
as done on i.MX.

this allow to check we do not exceed the size of the SRAM as example
introduce BAREBOX_MAX_BARE_INIT_SIZE the maximum size of bare_init
this will allow your bare_init will fit in SRAM as example
ARCH can overwrite it via ARCH_BAREBOX_MAX_BARE_INIT_SIZE

to copy only the image size if barebox is stored on
raw partitions which are bigger than the image.

The flash header is used on different i.MXs other than the
i.MX25, so rename it. Also, add a possibility to put a flash
header on different offsets (0x100, 0x400 and 0x1000), needed
for different boot mediums.

Memory layout can now be specified via kconfig options. Two
possibilities exist: default layout means the layout is stack
/ malloc heap / U-Boot. The user can also specify fixed addresses
for each TEXT_BASE / stack / malloc heap.
exported symbols. Using kallsyms for this purpose doesn't do it because
kallsyms do not resolve variables. Also the symbol table gets quite
big using kallsyms.
- Add help texts for many commands.
- Let the linker sort the command table.
- Add support for multiple argmuments in several commands
(mkdir, rmdir, rm, cat)
