Ulf Magnusson 4e85006ba4 dts: Rename generated_dts_board*.{h,conf} to devicetree*.{h,conf}
generated_dts_board.h is pretty redundant and confusing as a name. Call
it devicetree.h instead.

dts.h would be another option, but DTS stands for "devicetree source"
and is the source code format, so it's a bit confusing too.

The replacement was done by grepping for 'generated_dts_board' and
'GENERATED_DTS_BOARD'.

Two build diagram and input-output SVG files were updated as well, along
with misc. documentation.

hal_ti, mcuboot, and ci-tools updates are included too, in the west.yml
update.

Ulf Magnusson def1f0e2d5 devicetree: Remove DT_SRAM_{BASE_ADDRESS,SIZE}, use CONFIG_* versions
The SRAM address and size are currently available as both
DT_SRAM_{BASE_ADDRESS,SIZE} and as CONFIG_SRAM_{BASE_ADDRESS,SIZE} (via
the Kconfig preprocessor).

Use the CONFIG_SRAM_* versions everywhere, and remove generation of the
DT_SRAM_* versions from gen_defines.py.

The Kconfig symbols currently depend on 'ARC || ARM || NIOS2 || X86'.
Not sure why, so I removed it.

It looks like no configuration files set CONFIG_SRAM_* at the moment, so
another option might be to use the DT_* symbols everywhere instead. Some
Kconfig.defconfig.series files add defaults to them though.

Also improve the help texts for CONFIG_SRAM_* to say that they normally
come from devicetree rather than configuration files.

Daniel Leung e73231f7f0 toolchain: xcc: use Clang if exists
The XCC toolchain may come with Clang front-end depending on
how it's built. Currently, the only SoC/board using XCC is
the intel_s1000_crb and its XCC toolchain comes with Clang
3.9.0 which has a lot better support for C99 and C++11 than
the portion based on GCC 4.2 (which does not even support
C++11). So this change attempts to use the Clang portion
instead of GCC if the Clang executable exists.

Daniel Leung 24b9542eba soc: intel_s1000: fix XCC build error when CONFIG_LOG_MINIMAL=y
During LOG_*() macro expansions, XCC expands everything even though
IS_ENABLED() is used. This resulting in various log*() functions
(e.g. log_0(), log_1(), etc.) being required for linking. However,
when CONFIG_LOG_MINIMAL=y, those functions are not compiled from
the logging subsystem. Therefore, to get past the linking error,
dummy versions are being provided.

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.

The i2s_cavs.c driver manipulates cache lines before commencing
any DMA transfers. With write-back cache, if the DMA receive
buffer is not aligned to the cache lines, the data around
the buffer will be invalidated and may never written to memory.
Since the driver takes an external memory slab as buffer and
there is no easy way to force cache line alignment on
the application side, set the cached region to write-through
to avoid potential issue.

Andrew Boie 4e5c093e66 kernel: demote K_THREAD_STACK_BUFFER() to private
This macro is slated for complete removal, as it's not possible
on arches with an MPU stack guard to know the true buffer bounds
without also knowing the runtime state of its associated thread.

As removing this completely would be invasive to where we are
in the 1.14 release, demote to a private kernel Z_ API instead.
The current way that the macro is being used internally will
not cause any undue harm, we just don't want any external code
depending on it.

The final work to remove this (and overhaul stack specification in
general) will take place in 1.15 in the context of #14269
