This patch adds support for extracting LZ4-compressed kernel images,
as well as LZ4-compressed ramdisk images in the kernel boot process.
This depends on the patch below

The compiled in dcd images generate an intermediate assembly file. Instead
of generating them as *.S generate them as *.dcd.S to better identify them
as generated files. These are then added to .gitignore.

This adds host tools for i.MX to generate the i.MX internal
flash header format and a tool to upload these images to an
i.MX SoC via USB.

kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp
Replace cmd_dtc with cmd_dtc_cpp, and delete the latter.
Previously, a special file extension (.dtsp) was required to trigger
the C pre-processor to run on device tree files. This was ugly. Now that
previous changes have enhanced cmd_dtc_cpp to collect dependency
information from both gcc -E and dtc, we can transparently run the pre-
processor on all device tree files, irrespective of whether they
use /include/ or #include syntax to include *.dtsi.

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.

The lowlevel code is expected to be present only ONCE
in PBL is enabled otherwise in barebox
This fix the module support with PBL and allow to reduce the size of barebox
by drop the lowlevell init in barebox as the compiler does not discard it

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.
