The Xtensa L1 cache layer has straightforward semantics accessible via
single-instructions that operate on cache lines via physical
addresses. These are very amenable to inlining.
Unfortunately the Xtensa HAL layer requires function calls to do this,
leading to significant code waste at the calling site, an extra frame
on the stack and needless runtime instructions for situations where
the call is over a constant region that could elide the loop. This is
made even worse because the HAL library is not built with
-ffunction-sections, so pulling in even one of these tiny cache
functions has the effect of importing a 1500-byte object file into the
link!
Add our own tiny cache layer to include/arch/xtensa/cache.h and use
that instead.

Instead of passing the crt1 _start function as the entry code for
auxiliary CPUs, use a tiny assembly stub instead which can avoid the
runtime testing needed to skip the work in _start. All the crt1 code
was doing was clearing BSS (which must not happen on a second CPU) and
setting the stack pointer (which is wrong on the second CPU).
This allows us to clean out the SMP code in crt1.

Zephyr's normal architecture is to do all initialization in the
interrupt stacks. The CAVS code was traditionally written to start
the stack at the end of HP-SRAM, where it has no protection against
overlap with other uses (e.g. MP startup used the same region for
stacks and saw cache collisions, and the SOF heap lives in this area
too). Put it where Zephyr expects and we'll have fewer surprises.

The kernel passes the CPU's interrupt stack expected that it will
start on that, so do it. Pass the initial stack pointer from the SOC
layer in the variable "z_mp_stack_top" and set it in the assembly
startup before calling z_mp_entry().

There's no need to muck with the cache directly as long as we're
careful about addressing the shared start record through an uncached
volatile pointer.
Correct a theoretical bug with the initial cache invalidate on the
second CPU which was actually doing a flush (and thus potentially
pushing things the boot ROM wrote into RAM now owned by the OS).
Optimize memory layout a bit when using KERNEL_COHERENCE; we don't
need a full cache line for the start record there as it's already in
uncached memory.

The multiprocessor entry code here had some bits that look to have
been copied from esp32, including a clumsy stack switch that's needed
there. But it wasn't actually switching the stack at all, which on
this device is pointed at the top of HP-SRAM and can stay there until
the second CPU swaps away into a real thread (this will need to change
once we support >2 CPUS though).

There was a bunch of dead historical cruft floating around in the
arch/xtensa tree, left over from older code versions. It's time to do
a cleanup pass. This is entirely refactoring and size optimization,
no behavior changes on any in-tree devices should be present.
Among the more notable changes:
+ xtensa_context.h offered an elaborate API to deal with a stack frame
and context layout that we no longer use.
+ xtensa_rtos.h was entirely dead code
+ xtensa_timer.h was a parallel abstraction layer implementing in the
architecture layer what we're already doing in our timer driver.
+ The architecture thread structs (_callee_saved and _thread_arch)
aren't used by current code, and had dead fields that were removed.
Unfortunately for standards compliance and C++ compatibility it's
not possible to leave an empty struct here, so they have a single
byte field.
+ xtensa_api.h was really just some interrupt management inlines used
by irq.h, so fold that code into the outer header.
+ Remove the stale assembly offsets. This architecture doesn't use
that facility.
All told, more than a thousand lines have been removed. Not bad.

Since the uart device clock will be stopped after ec entered sleep or
deep sleep state and restore its clock automatically, there is no need
to implement code for suspending and resuming devices manually.
The driver still needs to check the current status of uart device when
it wants to change its power state to LOW or SUSPEND power state. It is
crucial to forbid ec enters sleep or deep sleep state when uart device
is busy with transmitting data. Or we will observe broken characters on
the uart console.

This CL introduces power management driver that improves the efficiency
of ec operation by adjusting the chip’s power consumption to the level
of activity required by the application in npcx series.
The following list summarizes the main properties of the various chip
power states. Please refer the power.c file for more detail.
Main power states in npcx series include:
- Active: Core, RAM and modules operate at the clocks generated by PLL.
- Idle: Enter this state when the Core executes WFI or WFE instruction.
- Sleep: clock is stopped for most of modules but PLL is enabled.
- Deep Sleep: As Sleep mode but PLL is disabled.
- Standby: All power rails are turned off besides standby and battery
power rails.
And this CL implements one power state, PM_STATE_SUSPEND_TO_IDLE, with
two sub-states for Zephyr power management system.
Sub-state 0 - "Deep Sleep" mode with “Instant” wake-up if residency
time is greater or equal to 1 ms
Sub-state 1 - "Deep Sleep" mode with "Standard" wake-up if residency
time is greater or equal to 201 ms

This CL introduces a kernel device driver implemented by the internal
64/32-bit timers in Nuvoton NPCX series. Via these two kinds of timer,
the driver provides an standard "system clock driver" interface.
It includes:
- A system timer based on an ITIM64 (Internal 64-bit timer) instance,
clocked by APB2 which freq is CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC.
- Its prescaler is set to 1 and provide the kernel cycles reading
without handling overflow mechanism.
- A event timer based on an ITIM32 (Internal 32-bit timer) instance,
clocked by LCLK which frequency is 32KHz and still activated when ec
entered "idle/deep idle" power state for better power consumption.
- Its prescaler is set to 1 and provide timeout event mechansim.
- Compensate system timer which clock is gating for better power
consumption after ec left"idle/deep idle" power state.
This CL passed starve, timer_api, and timer_monotonic test suites.

The default frequency for this board in Renode is 66 MHz. This needs to
be even with `SYS_CLOCK_HW_CYCLES_PER_SEC` to avoid such problems as in
the #31726 issue.
Unfortunately, the difference in these values was helpful for some tests
that are failing with 66 MHz set in both places. It created artificial
boost in certain circumstances.
The frequencies in the default Renode platform description (`.repl`)
file for MI-V were overridden with 4 MHz value that seems to be better
tolerated based on testing. The `SYS_CLOCK_HW_CYCLES_PER_SEC` was
adjusted as well.
To solve the rest of the issues, `cpu PerformanceInMips` was set to 4.
It seems tests are completed faster with such a value.
