Andy Ross bf531ac4fc drivers/timer: Add default z_clock_set_timeout() fallback
Useful for tick-only drivers like Pulpino that don't support this.
Ideally we'd have a header-level interface definition for individual
timer drivers to eliminate the noop function call, but this is clean
for now (even the Pulpino hardware looks like it should support
timeouts just fine, so effort would be better spent there than on a
clean "ticked" interface).

Andy Ross 1a1a9539ea include/system_timer.h: Timer API cleanup
Rename timer driver API functions to be consistent.  ADD DOCS TO THE
HEADER so implementations understand what the requirements are.
Remove some unused functions that don't need declarations here.

Also removes the per-platform #if's around the power control callback
in favor of a weak-linked noop function in the driver initialization
(adds a few bytes of code to default platforms -- we'll live, I
think).

Andrew Boie f253af2d30 drivers: timer: init earlier in boot sequence
By the time we get to POST_KERNEL, kernel services and kernel objects
should be available for use. This should include timers and the random
number generator, but we don't init the system clock until sometime
during the POST_KERNEL phase. Initialize it earlier.

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 0b474eef9c kernel: deprecate old init levels
PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.

New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.

Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

Dmitriy Korovkin 661d2f3a16 microkernel: Add support for *_sleep() during initialization
Add support for task_sleep() and fiber_sleep() during the
system initialization. When CONFIG_NANO_TIMEOUTS defined,
before the k_server() starts, kernel uses nanokernel
system clock announce and task sleep functionality.

To give device drivers early sleep functionality, the system
clock has to start on SECONDARY initialization level, same
as most of the drivers.

Benjamin Walsh e893869435 Revert "sys_clock: start the microkernel ticker in the MICROKERNEL init level"
This reverts commit 3c66686a43.

That commit fixed announcing ticks before the microkernel was up, but
prevented devices initializing before the MICROKERNEL level from having
access to the hi-res part of the system clock, which they could not poll
anymore.

Benjamin Walsh 3c66686a43 sys_clock: start the microkernel ticker in the MICROKERNEL init level
The ticker was always initialized in the NANOKERNEL init level. In a
microkernel, this can cause problems if for the some reason the
initialization of the microkernel server is delayed, such as devices
initialization in the NANOKERNEL level taking non-insignificant time to
complete. What happens in that case is the ticker ISR will start firing
and piling up events in the microkernel server stack, and quite quickly
overrun it, since it has a finite size, causing random crashes.

So, in the microkernel, initialize the ticker once the microkernel
server is available. There is no point in sending ticker event before
anyway.

Dmitriy Korovkin 93b0ced44b Order hardware and device initialization
The initialization procedures need to be called in the
following order:
- basic hardware initialization;
- devices initialization;
- hardware clock initialization, that the kernel needs to
  run the kernel server.
This way, the board initialization routines is placed
to the pure_early_init level to make sure it runs first,
all device initialization procedures run at pure_init level,
so they are initialized early enough to be used for debugging
if needed. Hardware clock initialization is placed on
nano_early_init level to make sure hardware clock is initialized
just before the kernel server starts.
