Ramakrishna Pallala 12d614d0b8 drivers: gpio: add support for Altera Nios-II PIO controller
The PIO cores on Altera Nios-II processors can be used
for GPIOs and each PIO core can be configured as Input only,
Output only or as Bidirectional port from the Qsys tool.

The present Nios-II softcpu image on the Zephyr only has the
support for Output only port and the PIOs[0:3] are wired to
LED[0:3] on the Altera MAX10 board.

Ramakrishna Pallala 27aced168d arch: nios2: enable System ID soft IP driver
The system ID core is a simple read-only device that
provides Qsys systems with a unique identifer.

Nios-II processor systems use the system ID core to
verify that an executable program was compiled targeting
the actual hardware image configured in the target FPGA.

Ramakrishna Pallala 47595b1c10 boards: nios2: fix nios2 flashing issue
'make flash' is failing for altera_max10 board due to the
missing NIOS2_CPU_SOF environment variable. Though it is set
in arch/nios2/soc/nios2f-zephyr/CMakeLists.txt but it is not
taking effect when flashing script is run. The reason could be
following which is mentioned in https://itk.org/Wiki/CMake_FAQ

"environment variables SET in the CMakeLists.txt only
take effect for cmake itself (configure-time), so you cannot use
this method to set an environment variable that a custom command
might need (build-time)."

Now, NIOS2_CPU_SOF is set from boards/nios2/altera_max10/board.cmake
file which is more logical because all the FLASH related environment
variables are being set from board.cmake

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.

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
