This removes the z_ prefix those (functions, enums, etc.) that
are being used outside the coredump subsys. This aligns better

This adds two new APIs to the coredump subsystem to perform
query and command. These can be used to query coredump subsys
for information, and to perform commands such as finding
out if there is a stored coredump.

The coredump frontend (mostly) consists of wrappers of backend
functions so there is really no need to track errors at
the frontend level. Let the backends deal with their own errors
and this simplifies the code a bit.

Upcoming changes from Andrew that add a global timeout to the kernel
broke because of some voodoo behavior in the kernel/context test. It
will use arch_irq_disable() on the timer interrupt directly to prevent
interrupts and measure timekeeping in their absence. But some
architectures[1] don't reliably deliver interrupts that arrive, which
means that a running timeout that exists across this period will
result in a corrupt timeout queue.
Document that rule for architectures, move the offending test to the
end of the test suite (to minimize the chance of interacting with
other test code) and put a giant warning about the situation on it.
Long term, we may want to rework this test to do its job in other
ways.
[1] On x86, the interrupt disable happens at the IO-APIC level, while
interrupt latching and delivery is downstream in each CPU's Local
APIC. An IO-APIC masked interrupt is completely invisible to the APIC
and can never be delivered once the line goes low.

Following the idiom used for system calls, add script support to read
the initial application binary to identify which devices are defined,
and to use their offset in the device array as their unique handle
rather than the externally-defined ordinal from devicetree. The
device dependency arrays are updated to use these handles.

Generate arrays of dependency information for each device. If a
device definition is being constructed from devicetree these come from
the devicetree dependency information. Additional dependencies may be
passed through using the DT_ macros.
Define flag values for device handles so we can partition the
dependency array into distinct sets, which include things it requires,
things it supports (may not be needed), and child nodes (not
implemented, may not be needed).

This emulator pretends a generic eSPI Host. It supports basic virtual
wires and port80 operations.
There are functions to trigger actions on the host side e.g. for

emul_espi_host_send_vw. It will prepare data and set a proper event
on the slave side which will trigger callback (if there is any).

This patch implements a service that adds multiendpoint

when multiple modules need services from a remote processor. Each

The implementation separates backend from the service, what

The only two supported operations for data caches in the cache framework
are currently arch_dcache_flush() and arch_dcache_invd().
This is quite restrictive because for some architectures we also want to
control i-cache and in general we want a finer control over what can be
flushed, invalidated or cleaned. To address these needs this patch
expands the set of operations that can be performed on data and
instruction caches, adding hooks for the operations on the whole cache,
a specific level or a specific address range.

Firmware implementing the PSCI functions described in ARM document
number ARM DEN 0022A ("Power State Coordination Interface System
Software on ARM processors") can be used by Zephyr to initiate various
CPU-centric power operations.
It is needed for virtualization, it is used to coordinate OSes and
hypervisors and it provides the functions used for SMP bring-up such as
CPU_ON and CPU_OFF.
A new PSCI driver is introduced to setup a proper subsystem used to
communicate with the PSCI firmware, implementing the basic operations:
get_version, cpu_on, cpu_off and affinity_info.
The current implementation only supports PSCI 0.2 and PSCI 1.0
The PSCI conduit (SMC or HVC) is setup reading the corresponding
property in the DTS node.
