bd985dcd67 drivers: add GIC V3 driver
Add basic driver for GIC V3 interrupt controller.

This implementation supports
 - distributor, re-distributor and cpu interface initialization
 - configuration and handling of SPI, PPI and SGI.
 - V2 Legacy mode is not supported and uses system interface.

Current implementation supports GIC secure state only.
All interrupts are routed to Secure EL1 as 'irq' by configuring
them as Group1 Secure.

TODO:
- MPIDR based affinity routing setting.
- percpu redistributor probe
- message based SPI and SGI generation api
- EL1NS support. Legacy mode support.
- LPI/ITS is not supported.

2b441732ff interrupt_controller: gic: Support multiple GIC versions
The current GIC driver implementation only supports the GIC-400, which
implements the GICv2 interface.

This commit refactors the GIC driver to support multiple GIC versions
and adds GICv1 interface support (GICv1 and GICv2 interfaces are very
similar).

c30600d4ab drivers/interrupt_controller: Adopt file naming as other drivers
Pattern being <domain>_<model>.<c/h>.
Here interrupt_controller as a domain would be far too long so
shortening it to "intc", as DTS does actually.

571d3b54db interrupt_controller: gic: Add support for the GIC400
The GIC400 is a common interrupt controller that can be used with the
Cortex A and R series processors.  This patch adds basic interrupt
handling for the GIC, but does not handle multiple routing or
priorities.

3dc7c7a6ea drivers/interrupt_controller/mvic.c: remove MVIC interrupt controller
The Quark D2000 is the only x86 with an MVIC, and since support for
it has been dropped, the interrupt controller is orphaned. Removed.

6aedb6ff1a arch/x86: disable i8259 in crt0.S
drivers/interrupt_controller/i8259.c is not a driver; it exists
solely to disable the i8259s when the configuration calls for it.
The six-byte sequence to mask the controllers is moved to crt0.S
and the pseudo-driver is removed.

4462069d74 drivers: gpio: sam0: Add interrupt support
This adds interrupt support to the SAM0 GPIO driver.  This is heavily
inspired by @nzmichaelh work in #5715.  The primary difference
from that implementation is that here the External Interrupt
Controller (EIC) is separated out into an interrupt controller driver
that is less tightly coupled to the GPIO API.  Instead it implements
more of a conversion from the EIC's own odd multiplexing to a more
traditional port and pin mask IRQ-like callback.  Unfortunately,
through the EIC on the SAMD2x are relatively well behaved
in terms of pin to EIC line mappings, other chips that share the
peripheral interface are not.  So the EIC driver implements a
per-line lookup to the pin and port pair using definitions extracted
from the ASF headers.

The EIC driver still makes some assumptions about how it will be used:
mostly it assumes exactly one callback per port.  This should be fine
as the only intended user is the GPIO driver itself.

This has been tested with some simple programs and with
tests/drivers/gpio/gpio_basic_api on a SAMD21 breakout and an
adafruit_trinket_m0 board.

3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier
Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier.  Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.

By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

58d8afb476 interrupt_controller: RV32M1: add intmux driver / DT bindings
Add a level 2 interrupt controller for the RV32M1 SoC. This uses the
INTMUX peripheral.

As a first customer, convert the timer driver over to using this,
adding nodes for the LPTMR peripherals. This lets users select the
timer instance they want to use, and what intmux channel they want to
route its interrupt to, using DT overlays.

e3f2fa4f89 drivers: interrupts: introduce Designware interrupt controller
This interrupt controller is a designware IP that combines several
sources of interrupt into one line that is then routed to the parent
controller.

This implementation supports only the regular irqs with no support
for priority filtering and vectored interrupts. Firqs are also not
supported.

CAVS stands for "connected Audio, Voice and Speech". This IP supports
4 lines which can have a max of 32 interrupts each.

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
