Adithya Baglody be1cb961ad tests: benchmark: boot_time: Reading time stamps made arch agnostic
1. Changed _tsc_read() to k_cycles_get_32(). Thus reading the
time stamp will be agnostic of the architecutre used.
2. Changed the variable names from *_tsc to *_time_stamp.

Kumar Gala bf53ebf2c8 arch: convert to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.  There are few places we dont convert over to the new
types because of compatiability with ext/HALs or for ease of transition
at this point.  Fixup a few of the PRI formatters so we build with newlib.

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.

Benjamin Walsh c3a2bbba16 kernel: add k_cpu_idle/k_cpu_atomic_idle()
nano_cpu_idle/nano_cpu_atomic_idle were not ported to the unified
kernel, and only the old APIs were available. There was no real impact
since, in the unified kernel, only the idle thread should really be
doing power management. However, with a single-threaded kernel, these
functions can be useful again.

The kernel internals now make use of these APIs instead of the legacy
ones.

Peter Mitsis 5c01c09f4d nano_stack: Simplify nano_xxx_stack_pop() API family
Changes the nanokernel stack API so that the timeout parameter must be
specified when invoking nano_isr_stack_pop(), nano_fiber_stack_pop(),
nano_task_stack_pop() and nano_stack_pop().

This obsoletes the following APIs:
	nano_fiber_stack_pop_wait()
	nano_task_stack_pop_wait()
	nano_stack_pop_wait()

Note that even though the new API requires that the timeout parameter
be specified, there are currently only two acceptable values:
	TICKS_NONE and TICKS_UNLIMITED
This nanokernel option does not support CONFIG_NANO_TIMEOUTS.
