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

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Jira: ZEP-1457

Andrew Boie 4eee43d4d4 nios2-qemu: correct system.h
The emulator supports all the integer math instructions and has
the necessary registers for exception debugging.

Andrew Boie c613715322 nios2-qemu: use all available RAM
Use all available ram, cut in half for simulated RAM/ROM
regions. Some larger test cases did not fit in 64K for
non-XIP case.

Andrew Boie 543aa77392 nios2-qemu: fix CONFIG_XIP
It's all RAM, but we pretend the range 0x410000 - 0x420000
is the "ROM" region, and stuff gets copied into RAM starting
at 0x400000.

Andrew Boie a7b54980bd nios2: set appropriate compiler flags for math support
Nios II CPUs vary in configuration on whether they support
'mul', 'mulx', and 'div' family of instructions. The compiler
can be told to use GCC integer library routines instead if
needed.

Ideally we would just pull the configuration out of system.h,
but pulling include file #defines into the Make environment
will involve some build system work that is best left to a
later improvement.

We've decided to take this build-time approach rather than
handle unimplemented instruction exceptions, so remove the
hook in exception.S

Andrew Boie b8d7b0dfe7 nios2: properly set SYS_CLOCK_HW_CYCLES_PER_SEC
This is a workaround until we can modify the kernel to pull this
value out of system.h instead of Kconfig.
