ARM cores may have a per-core architected timer, which provides per-cpu
timers, attached to a GIC to deliver its per-processor interrupts via
PPIs. This is the most common case supported by QEMU in the virt
platform.
This patch introduces support for this timer abstracting the way the
timer registers are actually accessed. This is needed because different
architectures (for example ARMv7-R vs ARMv8-A) use different registers
and even the same architecture (ARMv8-A) can actually use different
timers (ELx physical timers vs ELx virtual timers).
So we introduce the common driver here but the actual SoC / architecture
/ board must provide the three helpers (arm_arch_timer_set_compare(),
arm_arch_timer_toggle(), arm_arch_timer_count()) using an header file
imported through the arch/cpu.h header file.

The initial prototypes for sys_trace_* are not needed

These actually cause linkage conflicts if CTF tracing is attempted

Similar to pairing_confirm this callback is called each
time a peer requests pairing, but for all types of
pairings, except SSP. The pairing req/rsp information is
passed as a parameter so the application can decide
wheter to accept or reject the pairing.

This commit fixes an issue observed with SimpleLink sockets with
multiple definitions of `gethostname` function. So far, the definition
within `socket.h` was not visible when offloading was enabled.
As this is no longer the case, and SimpleLink partially uses POSIX
subsystem, builds for this platform resulted in compilation error.
The issue was fixed by moving `gethostname` declaration in unistd.h
inside the `#ifdef CONFIG_POSIX_API` block.

Instead of using a custom offloading interface, users can use
`NET_SOCKET_REGISTER` macro to register custom socket API provider. This
solution removes a limitation, that only one offloaded interface can be
registered and that it cannot be used together with native IP stack.
The only exception remainig are DNS releated operations -
`getaddrinfo`/`freeaddrinfo`, which, when offloaded, have to be
registered specifically.

Instead of having TI_CCFG_PRESENT as a symbol that's only defined in
soc/arm/ti_simplelink/cc13x2_cc26x2/Kconfig.defconfig.series and y when
SOC_SERIES_CC13X2_CC26X2 is enabled, turn it into a helper symbol that's
selected by SOC_SERIES_CC13X2_CC26X2.
This avoids having a symbol that's only defined in a Kconfig.defconfig
file, which is confusing. It also makes things a bit more generic, in
case other boards with CCFGs are added.
Also rename it to HAS_TI_CCFG to be consistent with other helper
symbols, and add a help text.

There are various situations where it's necessary to support turning
devices on or off at runtime, includin power rails, clocks, other

Introduce a new counter API function for reading the current counter
value (counter_get_value()) and deprecate the former counter_read() in
favor of this.
Update all drivers and calling code to match the new counter API.
The previous counter driver API function for reading the current value
of the counter (counter_read()) did not support indicating whether the
read suceeded. This is fine for counters internal to the SoC where the
read always succeeds but insufficient for external counters (e.g. I2C
or SPI slaves).

In zephyr_linker_sources().
This is done since the point of the location is to place things at given
offsets. This can only be done consistenly if the linker code is placed
into the _first_ section.
All uses of TEXT_START are replaced with ROM_START.
ROM_START is only supported in some arches, as some arches have several
custom sections before text. These don't currently have ROM_START or
TEXT_START available, but that could be added with a bit of refactoring
in their linker script.
No SORT_KEYs are changed.
This also fixes an error introduced when TEXT_START was added, where
TEXT_SECTION_OFFSET was applied to riscv's common linker.ld instead of
to openisa_rv32m1's specific linker.ld.

This commit does the following:
- renames the 'text' ROM section to 'rom_start', to reflect
that this section is the first section of the image.
- renames the 'TEXT_SECTION_NAME_2' section to 'text', since
that section (whose start is pointed by _image_text_start)
holds the entire image text section.
The commit removes the confusion by having multiple ROM sections
named as 'text' in ARM Cortex-M builds.

It's possible for a thread to abort itself simultaneously with an
external abort from another thread. In fact in our test suite this is
a common thing, as ztest will abort its own spawend threads at the end
of a test, as they tend to be exiting on their own.
When that happens, the thread marks itself DEAD and does all its
scheduler bookeeping, but it is STILL RUNNING on its own stack until
it makes its way to its final swap. The external context would see
that "dead" metadata and return from k_thread_abort(), allowing the
next test to reuse and spawn the same thread struct while the old
context was still running. Obviously that's bad.
Unfortunately, this is impossible to address completely without
modifying every SMP architecture to add a API-visible hook to every
swap that signals completion. In practice the best we can do is add a
delay. But note the optimization: almost always, the scheduler IPI
catches the running thread and kills it from interrupt context
(i.e. on a different stack). When that happens, we know that the
interrupted thread will never be resumed (because it's dead) and can
elide the delay. We only pay the cost when we actually detect a race.

CPU exceptions, with KPTI turned on, are treated as interrupts
