NPCX7/9 has a different ADC register structure. NPCX7 has 3 threshold
detectors from offset 0x14 & has 10 input channels. NPCX9 has 6
threshold detectors from offset 0x60 & has 12 input channels.
This commit fixes the NPCX ADC register structure.

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 MP startup code had a hardcoded INTLEVEL field of 5 in the initial

The CAVS linker scripts in Zephyr and "plain" (XTOS) SOF seem to share
the same origin and they mostly duplicate each other so they naturally
keep diverging from each other. This commit catches up with the SOF
commit ef43899c580f (thesofproject/sof/pull/2996) which added
the *(.trace_ctx) sections as part of the runtime log filtering
implementation (feature request thesofproject/sof/issues/2172)
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.
Together with some other changes in SOF, these 3 additional lines are
enough change in Zephyr to fix SOF bug thesofproject/sof/issues/5032

comments, there are deliberate empty sections in this link that

populated and rimage has non-code sections that may be left empty for
non-audio-driver applications like tests.

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.

The module copy was clearing BSS sections from the module list, but we
already clear the full memory space immediately after SRAM power-up so
that's needless, just like the legacy reset vector bss clear that got
removed earlier. (Yes: that means that this code used to be writing
zeros to .bss three times!)
Similarly, put a symmetric clear on the LP-SRAM bank for safety (it's
not currently used by Zephyr but we do start it up). And move the
cache flush to the end of initialization immediately before OS
handoff.

This is some SOF code that got imported into Zephyr. But it's not a

Syntax beautification and general simplification pass:
+ Remove some spurious padding around the _data_end symbol. That's a
Zephyr symbol and should reflect the actual end of the data section in
bytes.
+ Squash a warning that crept in where the linker doesn't like
changing cache mapping and padding at one time, clarify in docs.
+ Use the pre-existing-but-heretofore-unknown-to-me Zephyr
debug-sections.ld include file instead of putting all the DWARF
sections in by hand.
+ Move the .xt* sections to explicit zero addresses, since that's what
debug-sections.ld does for its output and if I don't they'll end up
with funny values.
+ Use Zephyr brace-on-same-line style consistently
+ Remove cargo-cult noop patterns like ALIGN(4) and ABSOLUTE(.) (none
of these sections get furthur relocated!)
+ Clean up the SEGSTART_* API so that it doesn't need to have
CONFIG_KERNEL_COHERENCE guards.
+ Remove a few unused/legacy symbol exports ("end", "__stack") so as
not to pollute the namespace.

This header is now included in only one place, and just contains a

Lots of changes to the linkage, none major:
+ Remove all the manually-defined ELF program headers. This was a big
pain to maintain, and I finally figured out why we were doing this:
it turns out to have been a workaround for the flags issue below.
+ Suppress the "empty loadable section" warnings at module generation.
This turns out to be an objcopy issue, when you drop all the
sections from an ELF program header.
+ Set section flags for NOLOAD sections manually. Rimage is very
strict about flags (even to the point of trying to suck in its own
metadata section as program text). This turns out to be really
fragile, as the linker automatically sets flags on the output
section based on the symbols placed in it. Rather than needing to
have one program header per section, or playing games in the
assembly for section definition to make this all match, just set the
flags expressly on the sections we know about on the objcopy command
line.
+ Similarly drop the special memory regions with explicit faked
"physical" addresses that were being used for non-loadable sections
(e.g. .fw_metadata, .static_log_entries). Just link them all after
the rest of the image like other platforms do.
+ Clean up multiple levels of macro indirection for the manifest base
address, which is ultimately coming from kconfig. Now the magic
numbers don't seem so magic.
+ Remove legacy symbol exports for "cacheattr" that we don't use
anymore.

There was a ". = ALIGN(4096);" sitting at the end of the .text section
in the linker. This had the effect of needlessly padding the size of
the segment as packed into and copied out of the firmware DMA image.
There's no value to storing unused bytes in the image. It also makes
analysis easier for changes the modify code size. The following
.rodata section was already being 4k aligned anyway.

The bootloader had always been doing setup for window 0 (the firmware
status word reported to the loader). This then got needlessly
repeated in the main OS startup. Drop that, and move window 3 setup
(the trace/printk output buffer) there too for symmetry.
This means that the clear and cache flush of the buffer can be handled
in only one place too, for some runtime win (before it was being
cleared/flushed once at SRAM initialization time and then again at
window setup).
And as that was the only task remaining in the "adsp.c" file, we can
just remove it entirely.
One nice side effect is that this pushes up the point where we can get
a successful printk() out all the way back into the later stages of
the bootloader.

Now that we have access to IMR memory for non-bootloader tasks, let's
pick the low hanging fruit. SOC code that is only used at
initialization time (or things like core halt/restart which happen
only in non-realtime contexts) are now flagged __imr.
This is good for 808 bytes of code moved out of the main Zephyr image
on cavs_v25.
In the medium term, it would be good to define a system define for
this purpose (a-la Linux __init/__initdata) and start moving core
Zephyr init code too.

The Zephyr symbols are now part of the same link as the bootloader, so
no need to have an assembly entry stub or fixed address at all. Just
call z_cstart() as a normally-relocated function. Interestingly
Zephyr never put a declaration for it in public headers, because this
appears to be the first platform calling it from C.

Now that the IMR boot code is built as part of the main Zephyr

The presence of a separate build for the bootloader code has always
been a wart with this platform. Sharing of code between the two has
required great care. We've had bugs with mismatched include paths,
macro definitions and compiler flags, etc... And of course it's not
possible for one to see the other; in theory we'd like the ability to
call back into IMR code after startup, to use the space for temporary
storage, etc...
So let's finally do it. This really isn't that complicated when you
see it in isolation:
+ Move the module manifest metadata into an "rimage_modules.c", and
put them in their own NOLOAD section where we can grab them later
with objcopy.
+ Make a new "imr" memory region in the main linker and just paste the
bootloader linkage (which is now using its own specific sections) in
there.
+ After zephyr.elf is built and cache-remapped, we can extract the imr
sections and the appropriate manifest for the bootloader rimage
module, and then do the converse by excluding them for the main
image module.

Define an __imr attribute macro that allows the bootloader to
expressly specify symbosls to go into IMR memory, use it pervasively
in the bootloader code, and remove the traditional section names from
boot_ldr.x.
This doesn't do anything by itself, but it is a necessary step for
getting the bootloader and Zephyr code to live together in the same
link.
