4fa68ba67a soc: intel_adsp: remove logging defaults
We are enabling logging in the SoC, this should be an application
decision, not a hardware decision.
Additionally, we are disabling logging defaults for testing, which
results in some tests failing on those platforms due to missing messages
in the test output.

1b3d590e22 soc/intel_adsp: cavstool: poll FW_STATUS even when --log-only
Failures to boot are not exclusive to the cavstool.py, they can happen
with the kernel driver and --log-only too. For such a situation this
commit adds a useful delay and these two log lines (before the mmap
crashes eventually):

1e9ada4eb9 dma: cavs: Add gpdma derivative of dw dma for cavs
Intel's adsp needs to set, at a minimum, a clocking bit before the driver
can initialize the designware dma controller. In many ways it is the
designware dmac IP but with additional registers and functionality added
on top of it. So the code structure here follows how the hardware
appears to be designed, layered on top of the designware driver.

140837ce3a soc/intel_adsp: DMA Stability fix for cavstool
There is a hardware bug with stream reset, it won't stop the stream.
I thought it was limited to just the early versions, but it turns out
that 2.5 has it too in some variants.  Which is frustrating, because
the TGL chromebook I have doesn't like the START clear.  But all
systems work with an extra delay between them, so do that.

dbff5861c4 soc/intel_adsp: Fixups for cavs18 SMP boot
This platform was stale for a long time and got a little left behind.
Basic OS stuff was working but secondary core bringup didn't.  It has
a slightly different set of choices from the "weird hardware
quirks" menu:

+ Like cAVS 1.5, it boots from a ROM that needs a short delay after
  power-up before it can receive the startup IDC.

+ But, like 2.5 and unlike 1.5, it doesn't start running until the
  PWRCTL bit for the core gets set by DSP software (1.5 gets launched
  by the host).  So the delay needed to move down a bit.

+ It wants that PWRCTL bit to be set last, after CLKCTL enables the
  clock.  (Which makes sense I guess: EE classes always tell you hold
  circuits in reset while an initial clock propagates). Not sure why
  it was in the reverse order originally; this way works for
  everything.

+ The ROM likes to scribble on the interrupt controller and mask its
  own IDC interrupts after we've already set it up.  They have to be
  unmasked.  We had code to do this already, thinking it was a
  workaround for legecy SOF code (that we never actually located).
  Now I'm thinking it was this behavior all along being detected by
  SOF's more extensive hardware CI.  Take out the test and do it
  always, it's like nine instructions.

+ The host/loader-side behavior is a mix of 1.5 and 2.5.  It won't
  actually start the secondary cores under host command, but it does
  need to see bits set for them in ADSPCS for the DSP-initiated
  power-up to work (2.5 would just ignore all but core 0's bits).

+ Also, like 1.5, it needs the host DMA stream to be explicitly
  stopped (and not just reset) or else further loads will be unstable.

Note that the loader changes now require more logic than just "1.5 or
not", so the platform detection has been enhanced to fully categorize
the device based on PCI ID (not quite: we don't have any 2.0 platform
hardware, so I left that alone for now).

f581d59821 soc/intel_adsp: Add unified "cavstool" loader/logger script
The existing scripting for these platforms has gotten a little stale.
The loader had bifurcated into a v15 and v25 variant, both of which
lived in the cavs15 board directory.  Building off Shao Ming's
excellent (if somewhat surprisingly committed) rework to unify
unchanged parts of the scripts, let's finish the job.

This adds a "cavstool.py" script with the following advantages:

+ It's just one script for everything, with a single unified load
  process that works reliably on both 1.5 and 1.8+ hardware.

+ It runs on all cAVS platforms (with a compatible kernel, those
  requirements haven't changed)

+ It automatically emitts logging synchronously after loading,
  eliminating the race between adsplog.py and cavs-fw.py where you
  could see logging from a previous test run.

+ It automatically detects and unloads a linux kernel module managing
  the same device (even if SOF has renamed the module again, heh).

+ Timings have been tuned up in general, it's about 2 seconds faster
  to get to first log output now.

528bef2d22 lib/os: Add sys_winstream lockless shared memory byte stream IPC
It's not uncommon to have Zephyr running in environments where it
shares a memory bus with a foreign/non-Zephyr system (both the older
Intel Quark and cAVS audio DSP systems share this property).  In those
circumstances, it would be nice to have a utility that allows an
arbitrary-sized chunk of that memory to be used as a unidirectional
buffered byte stream without requiring complicated driver support.
sys_winstream is one such abstraction.

This code is lockless, it makes no synchronization demands of the OS
or hardware beyond memory ordering[1].  It implements a simple
file/socket-style read/write API.  It produces small code and is high
performance (e.g. a read or write on Xtensa is about 60 cycles plus
one per byte copied).  It's bidirectional, with no internal Zephyr
dependencies (allowing it to be easily ported to the foreign system).
And it's quite a bit simpler (especially for the reader) than the
older cAVS trace protocol it's designed to replace.

[1] Which means that right now it won't work reliably on arm64 until
we add a memory barrier framework to Zephyr!  See notes in the code;
the locations for the barriers are present, but there's no utility to
call.

97ada8bc04 arch/xtensa: Promote adsp RPO/cache utilities to an arch API
This is trick (mapping RAM twice so you can use alternate Region
Protection Option addresses to control cacheability) is something any
Xtensa hardware designer might productively choose to do.  And as it
works really well, we should encourage that by making this a generic
architecture feature for Zephyr.

Now everything works by setting two kconfig values at the soc level
defining the cached and uncached regions.  As long as these are
correct, you can then use the new arch_xtensa_un/cached_ptr() APIs to
convert between them and a ARCH_XTENSA_SET_RPO_TLB() macro that
provides much smaller initialization code (in C!) than the HAL
assembly macros.  The conversion routines have been generalized to
support conversion between any two regions.

Note that full KERNEL_COHERENCE still requires support from the
platform linker script, that can't be made generic given the way
Zephyr does linkage.

f4a0ea7b43 soc/intel_adsp: Correct errant ATOMCTL
This got broken during the cpu_init unification pass.  I appear to
have copied that zero out of code that initialized Zephyr on a
uniprocessor config somewhere.  But what it means is that any use of
the S32C1I instruction to store to any memory type will trap an
exception!  And even when CONFIG_MP_NUM_CPUS==1, we will emit code to
do that in the atomics layer when SMP=y.

That configuration ("SMP" with 1 cpu) is actually exercised by some
tests, including important ones like timer_api.  These got broken.
Fix.

Really it's never correct to have anything but 1:1:1 ("external RCW
transaction") on these CPUs.  All Intel cAVS processors have hardware
atomics support.  We owe it to all the code we'll run to make sure it
works as documented and doesn't explode.

the *(.trace_ctx) sections as part of the runtime log filtering

Paraphrasing that commit, the goal is to create at link time a C-like
array by regrouping scattered trace contexts so they can be iterated on.

66e2ba130f soc/intel_adsp: Unbreak xcc builds
Recent linker changes got ahead of the toolchain and started using
features not available in the binutils 2.23-based Xtensa toolchain.
Specifically:

+ The section arguments to objcopy don't accept wildcards.

+ It's not legal to have an ALLOC section emitted to a region outside
  a declared MEMORY space.  So various non-mapped sections populated
  by C structs have to be put somewhere with an explicit address.

+ The older linker won't automatically create an empty section just
  because you assigned to ".", so the Zephyr tests that lack a
  .fw_metadata section get rejected by rimage.  The fix here is a
  little clumsy: copy the section out of zephyr.elf into a
  (potentially-zero-length) temporary file, then add it back to
  main.mod as a final step.

75c8a0c902 soc/intel_adsp: Put a guard around CAVS_VERSION
This is some SOF code that got imported into Zephyr.  But it's not a
Zephyr API and Zephyr doesn't use it.  Unfortunately, the Zephyr
definition is now the one actually used at runtime in SOF, so we can't
remove it.

Put a guard around the definition so nothing else uses it until we get
it moved back home.
