Typically we have ARC core configurations where Fast IRQs (FIRQ) are
enabled together with multiple register files and those we have covered
by testing. But FIRQ & single register bank we only happen to have on
the older EMSK v2.2.it might be a good idea to add a similar
configuration to nSIM "boards" so that we keep it tested regularly.

nsim_em7d_v22 configuration is similar with em_staterkit_em7d_v22,
both configed with FIRQ & single register bank.

Martí Bolívar 6e8775ff84 devicetree: remove DT_HAS_NODE_STATUS_OKAY
Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:

- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
  for macros which are equivalent to
  DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name

Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.

This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Stephanos Ioannidis 0e6ede8929 kconfig: Rename CONFIG_FLOAT to CONFIG_FPU
This commit renames the Kconfig `FLOAT` symbol to `FPU`, since this
symbol only indicates that the hardware Floating Point Unit (FPU) is
used and does not imply and/or indicate the general availability of
toolchain-level floating point support (i.e. this symbol is not
selected when building for an FPU-less platform that supports floating
point operations through the toolchain-provided software floating point
library).

Moreover, given that the symbol that indicates the availability of FPU
is named `CPU_HAS_FPU`, it only makes sense to use "FPU" in the name of
the symbol that enables the FPU.

Same deal as in commit eddd98f ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for all symbols defined within defconfig
files. See that commit for an explanation.

Maybe 'if's were used originally to mirror the 'if's in the main Kconfig
files, and then it got copied around by people assuming 'if' must work
differently from 'depends on'. It doesn't match in every spot at least.
Better to keep it simple and just consistently use 'depends on' when
it's a single symbol/choice I think. Helps reinforce that 'if' isn't
magic too.

Verified by printing all Kconfig menu nodes (symbols, choices, menus,
etc.) before and after the change and diffing (should show no
difference).

Ulf Magnusson c5839f834b kconfig: Remove assignments to CONFIG_<arch> syms and hide them
All board defconfig files currently set the architecture in addition to
the board and the SoC, by setting e.g. CONFIG_ARM=y. This spams up
defconfig files.

CONFIG_<arch> symbols currently being set in configuration files also
means that they are configurable (can be changed in menuconfig and in
configuration files), even though changing the architecture won't work,
since other things get set from -DBOARD=<board>. Many boards also allow
changing the architecture symbols independently from the SoC symbols,
which doesn't make sense.

Get rid of all assignments to CONFIG_<arch> symbols and clean up the
relationships between symbols and the configuration interface, like
this:

1. Remove the choice with the CONFIG_<arch> symbols in arch/Kconfig and
   turn the CONFIG_<arch> symbols into invisible
   (promptless/nonconfigurable) symbols instead.

   Getting rid of the choice allows the symbols to be 'select'ed (choice
   symbols don't support 'select').

2. Select the right CONFIG_<arch> symbol from the SOC_SERIES_* symbols.
   This makes sense since you know the architecture if you know the SoC.

   Put the select on the SOC_* symbol instead for boards that don't have
   a SOC_SERIES_*.

3. Remove all assignments to CONFIG_<arch> symbols. The assignments
   would generate errors now, since the symbols are promptless.

The change was done by grepping for assignments to CONFIG_<arch>
symbols, finding the SOC_SERIES_* (or SOC_*) symbol being set in the
same defconfig file, and putting a 'select' on it instead.

See
https://github.com/ulfalizer/zephyr/commits/hide-arch-syms-unsquashed
for a split-up version of this commit, which will make it easier to see
how stuff was done. This needs to go in as one commit though.

This change is safer than it might seem re. outstanding PRs, because any
assignment to CONFIG_<arch> symbols generates an error now, making
outdated stuff easy to catch.

Ulf Magnusson 975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

Ulf Magnusson 2b61031c8f kconfig: Remove symbol types from Kconfig.defconfig files
Same deal as in commit 7fdb525754 ("kconfig: Use 'default' instead of
'def_bool' in Kconfig.defconfig files"), but I hacked Kconfiglib to also
find cases where the type is given separately as e.g.

    config FOO
            int
            default 3

Motivation (from a note in
https://docs.zephyrproject.org/latest/guides/kconfig/index.html):

    For a symbol defined in multiple locations (e.g., in a
    Kconfig.defconfig file in Zephyr), it is best to only give the
    symbol type for the "base" definition of the symbol, and to use
    'default' (instead of 'def_<type>' value) for the remaining
    definitions. That way, if the base definition of the symbol is
    removed, the symbol ends up without a type, which generates a
    warning that points to the other definitions. That makes the extra
    definitions easier to discover and remove.

It's also nice if 'def_bool' and the like turn into a semi-reliable flag
that the symbol is only defined in Kconfig.defconfig files. That might
be a sign that things could be cleaned up.

Will do a separate pass later to remove some symbols only defined in
Kconfig.defconfig files.

Peter Bigot 4a470114fa arc: rearrange for standard use of extern "C"
Consistently place C++ use of extern "C" after all include directives,
within the negative branch of _ASMLANGUAGE if used.

Remove extern "C" support from files that don't declare objects or
functions.

In arch/arc/arch.h the extern "C" in the including context is left
active during an include to avoid more complex restructuring.

Background from issue #17997:

Declarations that use C linkage should be placed within extern "C"
so the language linkage is correct when the header is included by
a C++ compiler.

Similarly #include directives should be outside the extern "C" to
ensure the language-specific default linkage is applied to any
declarations provided by the included header.
