barebox used to have its own include/dt-bindings with files copied
from the corresponding kernel files. Use upstream dt-bindings directly
instead.

If barebox is builded out-of-tree we don't find the autogenerated
autoconf.h because we search in the srctree.
With this patch we don't get this error message:
cc1: fatal error: /[...]/barebox/include/generated/autoconf.h: No such file or directory

This adds a target to generate environment files from directories.
These are compiled into the barebox binary.
use it as:
bbenv-$(CONFIG_SOMETHING) += my-environment
The directory containing the files to compile into the binary
should be named my-environment.
This can be accessed in C code later as:
extern unsigned char __bbenv_my_environment_start[];
extern unsigned char __bbenv_my_environment_end[];

kbuild: create directory for dir/file.o
When add a obj with dir to obj-y, like this
obj-y += dir/file.o
The $(obj)/dir not created, this patch fix this.
When try to add a file(which in a subdir) to my board's obj-y, the build
progress crashed.
For example, I use at91rm9200ek board, and in kernel dir run:
mkdir objtree
make O=objtree at91rm9200_defconfig
mkdir arch/arm/mach-at91/dir
touch arch/arm/mach-at91/dir/file.c
and edit arch/arm/mach-at91/dir/file.c to add some code.
then edit arch/arm/mach-at91/Makefile, change the following line:
obj-$(CONFIG_MACH_AT91RM9200EK) += board-rm9200ek.o
to:
obj-$(CONFIG_MACH_AT91RM9200EK) += board-rm9200ek.o dir/file.o
Now build it:
make O=objtree
Then the error appears:
...
CC arch/arm/mach-at91/board-rm9200dk.o
CC arch/arm/mach-at91/board-rm9200ek.o
CC arch/arm/mach-at91/dir/file.o
linux-2.6/arch/arm/mach-at91/dir/file.c:5:
fatal error: opening dependency file
arch/arm/mach-at91/dir/.file.o.d: No such file or directory
Check the objtree:
LANG=en ls objtree/arch/arm/mach-at91/dir
ls: cannot access objtree/arch/arm/mach-at91/dir: No such file or directory
It's apparently that the target dir not created for file.o
Check kbuild source code. It seems that kbuild create dirs for that in
$(obj-dirs). But if the dir need not to create a built-in.o, It should
never in $(obj-dirs).
So I make this patch to make sure It in $(obj-dirs)

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.

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.

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__
