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

This patch changes Quark SE power drivers to support multicore scenarios
e.g. both LMT and ARC core are enabled and manage power.
Handling LPS states in multicore scenarios are dead simple because LPS
states are core-specific states. It means that putting the LMT core in
LPS doesn't affect the ARC core, and vice-versa. DEEP_SLEEP state, on
the other hand, affects both cores since it turns power off from the SoC
and both cores are shutdown. It means that if LMT puts the system in
DEEP_SLEEP, ARC core is shutdown even if it is busy handling some task.
In order to support the multicore scenario, this patch introduces the
SYS_POWER_STATE_DEEP_SLEEP_2 state to both ARC and x86 power drivers.
On ARC, this state works as following:
1) Save ARC execution context;
2) Raise a flag to inform the x86 core that ARC is ready to enter in
DEEP_SLEEP;
3) Enter in the lowest core-specific power state, which in this case is
LPSS.
On x86, DEEP_SLEEP_2 is very similar to DEEP_SLEEP. The difference relies
in the post_ops() which calls _arc_init() in order to start ARC core so
it can restore its context.
This patch also adds the test/power/multicore/ directory which provides
sample application to x86 and ARC cores in order to easily verify the
multicore support. In test/power/multicore/README.rst you can find more
details regarding the applications.

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.

To customise test builds and support test related features such as time
stamps and a boot banner, introduce a Makefile variant that is dedicated
to testing.
Initially we introduce a new config overlay that is used for all tests, in
this case we enable BOOT_BANNER and BUILD_TIMESTAMP. This will print the
current version and the date, useful when reporting bugs and also an
indicator that the system has booted before the test has started.
For example:
[QEMU] CPU: qemu32

When going into DEEP_SLEEP mode, the ARC core now saves
its context. This includes:
- All core registers
- Stack pointer
- Program counter (restored by jumping to the restore code)
The arc reset code now checks if the GPS0 bit 2 is set.
This is similar to the behavior of the x86 core done by
the QMSI bootloader which is setting GPS0 bit 1 in order
to call the restore path instead of cold boot path.
The sample has been adapted in order to support the ARC.

The API to disable _sys_soc_resume notification is currently
called _sys_soc_disable_wake_event_notification. This is
misleading because it is possible that the ISR from which
_sys_soc_resume is called could be from a different interrupt
with higher priority that happened before interrupts were
enabled. More accurately, it is a notification of exit from
kernel idling after pm operations.

QMSI 1.3 natively supports restoring the SoC and peripherals
after sleep.
The Zephyr Power Management shim layer is updated
in order to support QMSI functions.
The following functions have been added:
void _sys_soc_set_power_state(enum power_state);
void _sys_soc_power_state_post_ops(void);
In order to fully support deep sleep, the function
_sys_soc_set_power_state now support saving and
restoring CPU context and returns to the application.
_sys_soc_set_power_state function also abstracts
QMSI cpu states and enable the application to choose
between C1/C2 or C2LP states.
The QMSI power states are mapped as follows:
SYS_SOC_POWER_STATE_CPU_LPS -> power_cpu_c2lp
SYS_SOC_POWER_STATE_CPU_LPS_1 -> power_cpu_c2
SYS_SOC_POWER_STATE_CPU_LPS_2 -> power_cpu_c1
SYS_SOC_POWER_STATE_DEEP_SLEEP -> power_soc_deep_sleep
SYS_SOC_POWER_STATE_DEEP_SLEEP_1 -> power_soc_sleep
The following functions have been removed:
void _sys_soc_set_power_policy(uint32_t pm_policy);
int _sys_soc_get_power_policy(void);
FUNC_NORETURN void _sys_soc_put_deep_sleep(void);
void _sys_soc_put_low_power_state(void);
void _sys_soc_deep_sleep_post_ops(void);
Those changes are propagated to the samples.
All calls to QMSI are removed.
