This patch adds support for using device tree configuration files for
configuring ARM platforms.
In this patch, only the FLASH_SIZE, SRAM_SIZE, NUM_IRQS, and
NUM_IRQ_PRIO_BITS were removed from the Kconfig options. A minimal set
of options were removed so that it would be easier to work through the
plumbing of the build system.
It should be noted that the host system must provide access to the
device tree compiler (DTC). The DTC can usually be installed on host
systems through distribution packages or by downloading and compiling
from https://git.kernel.org/pub/scm/utils/dtc/dtc.git
This patch also requires the Python yaml package.
This change implements parts of each of the following Jira:

Currently CONFIG_OMIT_FRAME_POINTER is a boolean and defaults to N,
which increases code size. This is intended to improve debugability
but on many architectures the use of this option does not actually
compromise debugging. Further the compiler already knows whether or not
omitting the frame pointer is harmful to debugging and its defaults
are selected accordingly.
By making this choice optional we can have a sane default on *all*
architectures by letting the compiler decide for us.
This patch significantly improves the default code generation on
arm (thumb), nios2 and arc. The benefit looks to be about between 5%
and 10% code size reduction depending upon architecture). x86 is
unaffected.

This will replace the current goal of 'make qemu' with 'make run' and

being architecture specific.
We should be able to add new boards that support some other type of

define their own options for the use type of emulation.
'make qemu' will still work, however it will be deprecated, starting

If a particular project needs to add additional data to the
binary image, in most cases the entire linker script needs to
forked into the project space, causing maintenance issues if
the main linker script is changed.
Now we add some Kconfig options to allow a project to specify
some additional linker scripts which get included by the main
one in a few key areas:
1) In the definition to the 'rodata' section, which can allow
additional data to be included in this ROM section.
2) In the definition to the 'datas' section, which allows
additional data to be included in this RAM section.
3) Arbitrary additional sections to be included at the end of
the binary.
For 1 and 2, this is useful to include data generated outside of
the normal C compilation, such as data structures that are created
by special build tools.
3 is useful for including arbitrary binary blobs inside the final
image, such as for peripheral or co-processor firmware.

For projects like JerryScript and Micropython we are starting to see
hybrid build systems emerge where the application (which targets a
variety of OSs and already includes a complex build system) is compiled
using the applications own build system before handing over to the
zephyr build system for the final link.
Currently the integration is becoming quite complex as the applications
build integration tries to figure out sane values for CC and CFLAGS.
Much of this complexity can be avoided if we allow the zephyr build
system to export its configuration in a manner that can easily be
consumed by the alien build system.

Several Zephyr SDK toolchains support multilibs.
Instead of hard-coding locations of the libraries, the proper/cleanest way
is to query the GCC compiler for the locations of libgcc and libc.
However, in order to do this, we need to ensure a certain order of
initialization in the Makefile:
1. Determine CROSS_COMPILE.
We cannot determine LIB_INCLUDE_DIR, TOOLCHAIN_CFLAGS yet, as we don't
know the KBUILD_CFLAGS yet.
2. Calculate KBUILD_CFLAGS using CROSS_COMPILE
KBUILD_CFLAGS often need the compiler to validate options, i.e:
KBUILD_CFLAGS += $(call cc-option,-mabi=aapcs -mthumb -mcpu=cortex-m0)
However, LIB_INCLUDE_DIR, TOOLCHAIN_CFLAGS should not be needed for this
3. Finally, using CROSS_COMPILE and KBUILD_CFLAGS determine LIB_INCLUDE_DIR,
TOOLCHAIN_CFLAGS by querying GCC using -print-libgcc-file-name and
-print-multi-directory command line options.
This change should only affect Zephyr SDK toolchains, all other toolchains
are expected to function as before.
