Anas Nashif 70d819b405 arm: soc: move arm SoCs to top-dir
Move the SoC outside of the architecture tree and put them at the same
level as boards and architectures allowing both SoCs and boards to be
maintained outside the tree.

Sebastian Bøe 347f9a0a2d cmake: LD: Specify the entry point in the linker scripts
The entry point can and therefore should be set by linker
scripts. Whenever possible one should express things in the source
language, be it .c or .ld, and not in code generators or in the build
system.

This patch removes the flag -eCONFIG_KERNEL_ENTRY from the linker's
command line and replaces it with the linker script command

ENTRY(CONFIG_KERNEL_ENTRY)

Ioannis Glaropoulos 059952c8e1 arch: arm: update compile options for DSP
This commit updates the compile options in cmake to distinguish
between ARMv8-M Mainline MCUs with or withouth the optional DSP
extension. A new Kconfig option: ARMV8_M_DSP, is introduced, to
signify the use of an ARMv8-M MCU with DSP support.

Paolo Teti 700e4bd2e8 ARM: -march compile option is not set
Removing ${} variable evaluation fixes the issue.

For sam4s_xplained:

Before:
/repos/zephyr/samples/hello_world/build$ make VERBOSE=1 | grep march
/repos/zephyr/samples/hello_world/build$

After:
/repos/zephyr/samples/hello_world/build$ make VERBOSE=1 | grep march
...
-mthumb -mcpu=cortex-m4 -march=armv7e-m

Sebastian Bøe 12f8f76165 Introduce cmake-based rewrite of KBuild
Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2+

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

$ cd build
$ make
