Torsten Rasmussen 36bb00d1f5 armclang: ARM Compiler C library support
Support for ARM Compiler C library.

This commit add support for the ARM Compiler C libary in:
- Kconfig
- libc/armstdc

A new Kconfig symbol is added to allow a toolchain to specify if they
support linking with the minimal C library.
Also the CMake variable `TOOLCHAIN_HAS_NEWLIB` is exported to Kconfig
so that CONFIG_NEWLIB_LIBS can only be enabled if the toolchain has
newlib.

The armclang toolchain selects the CMake scatter file generator and
disables support for the LD linker template which is not supported by
armlink.

For the ARM Compiler C library, a corresponding lib/libc/armstc/ folder
with a minimal implementation to work with the ARM Compiler C library
is added.

Torsten Rasmussen 761eada9d3 kconfig: cmake: CMake linker script generator symbol added
A "Linker script" choice group has been added to the linker options
menu.

The existing HAVE_CUSTOM_LINKER_SCRIPT config has been relocated inside
the linker script menu.

Two new entries has been created:
- LD template, for using the old ld template files together with the C
  pre-processor to create the final linker script.
- CMake linker generator, used for ARMClang / armlink toolchain.
  The CMake linker generator is also supported for LD linker scripts
  for the ARM architecture.

In CMake, the file cmake/linker/ld/target.cmake has been updated to
support the CMake LD linker generator.

Daniel Leung 6a006d71b7 kernel: add kconfig to say not all code/data is present at boot
With demand paging and pinned sections enabled, it is possible for
data to be brought into physical memory as required by current
execution context. However, the kernel still assumes that all data
pages are present at boot which may not be desirable for certain
scenarios. This introduces a new kconfig to specify that those
data pages other than the boot and pinned sections are not present,
and they would be paged in on demand.

Torsten Rasmussen 6be1b2af9b kconfig: soc and shield cleanup
Always source the Zephyr base soc and shield (board root) Kconfigs
directly from Kconfig instead of generated Kconfig files.

This has the benefit that it is no longer necessary to generate Kconfig
files to source SoC root and shield (board root) when no custom roots
are provided.

Also this cleans up the doc/CMakeLists.txt and ensures that the
doc/CMakeLists.txt is not getting out of sync with the Kconfig.cmake.

Daniel Leung 1310ad6b0e linker: add bits for pinned regions
This adds the necessary bits for linker scripts and source code
to specify which symbols need to be pinned in memory. This is
needed for demand paging as some functions and data must reside
in memory all the time and cannot be paged out (e.g. paging,
scheduler, and interrupt routines for functionality).

This is up to the arch/SoC/board to define the sections in
their linker scripts as the pinned section may need special
alignment which cannot be done in common script snippets.

Daniel Leung d812728ec4 linker: add bits for boot regions
This adds the necessary bits for linker scripts and source code
to specify which symbols are needed for boot process so they
can be grouped together.

One use of this is to group boot related code and data so these
won't interval with other kernel and application for better
caching.

This is a must for demand paging as some functions and data
must be available during the boot process and before the memory
manager is initialized. During this time, paging cannot be used
so symbols linked in virtual memory space are unavailable.

This is up to the arch/SoC/board to define the sections in
their linker scripts as section may need special alignment
which cannot be done in common script snippets.

Torsten Rasmussen 3673e288bd modules: introducing MODULE_EXT_ROOT to allow glue code in Zephyr repo
This commit introduces MODULE_EXT_ROOT which allows CMake and Kconfig
glue code to be placed outside of the Zephyr module repository.

This allows for placing glue code in Zephyr, but also allows users to
specify custom MODULE_EXT_ROOTs for glue code using either
`-DMODULE_EXT_ROOT` or `zephyr/module.yml` with
`build:settings:module_ext_root` settings.

MODULE_EXT_ROOT' is a list of directories, similar to other roots such
as BOARD_ROOT, DTS_ROOT, etc.
The Zephyr repo folder ${ZEPHYR_BASE} is always to the MODULE_EXT_ROOT
list as lowest priority.
For each MODULE_EXT_ROOT, the file
`<module_ext_root>/modules/modules.cmake` will be processed.

In Zephyr repo, the folder `modules/<module>/` contains CMakeLists.txt
and Kconfig glue code for the Zephyr module.

A Zephyr module can specify that CMakeLists.txt and Kconfig glue code is
placed in an external module root by specifying:
```
build:
  cmake-ext: True
  kconfig-ext: True
```

It is still possible to place the CMakeLists.txt and Kconfig files
directly in the Zephyr module using the existing:
```
build:
  cmake: <path>
  kconfig: <file>
```.

Martí Bolívar 8165008f44 dts: remove legacy macro support
The legacy macros were first deprecated in Zephyr v2.3. Now that
Zephyr v2.4 has been released, that makes two releases where these
macros have been deprecated, so it's OK to remove them.

This leaves support for legacy binding syntax in place. Removing that
is left to future work.

We need to update various pieces of documentation related to flash
partitions that never got updated when the new API was introduced.
Consolidate this information in the flash_map.h API reference page,
since that's really where users will run into it. This also gives us
the opportunity to improve this documentation.

- CONFIG_MCUBOOT_GENERATE_CONFIRMED_IMAGE: also generate
  zephyr.signed.confirmed.{bin,hex}

This commit introduces support for multiple SOC_ROOT.

This means that additional SOC_ROOTs specified using -DSOC_ROOT as

This allows for greater flexibility, as developers can now specify

board they compile for.

Also it avoid code, such as:
if(BOARD STREQUAL my_board_using_out_of_tree_soc)
  set(SOC_ROOT some/out/of/tree/soc/path)
endif()
in application CMakeLists.txt.

Finally, allowing multiple SOC_ROOTs prepares for specifying SOC_ROOTs

Martí Bolívar 270dfffc8d devicetree: add CONFIG_LEGACY_DEVICETREE_MACROS
This default-y option allows continued use of the legacy devicetree
macros.

There are no functional changes yet, but when this is default n,
old-style DT code won't build. At that point, adding any of these will
be a fix to keep old-style code working:

- "CONFIG_LEGACY_DEVICETREE_MACROS=y" to prj.conf
- "-- -DCONFIG_LEGACY_DEVICETREE_MACROS=y" to the west build command
- "-DCONFIG_LEGACY_DEVICETREE_MACROS=y" to the cmake command

This option can be changed to default n in time for the Zephyr 2.3
release. That will provide users of Zephyr 2.2 with a smooth migration
path to the new devicetree.h API after 2.3 is released, which
nonetheless will alert them immediately that something is wrong due to
build errors.

Unfortunately, __DEPRECATED_MACRO is not sufficient in all cases as a
warning to users. This is because, at least in GCC, macros defined
using __DEPRECATED_MACRO cannot be used in preprocessor lines like
"#if DT_SOME_LEGACY_MACRO".

Kumar Gala 2630fbaa75 cmake: Introduce optional Kconfig for toolchains
Allow a given toolchain to specify Kconfig options that might be
relevant to a feature available in that toolchain.

For example, the ARM embedded GNU toolchain supports two variants of
newlib and you select the smaller one via a spec file.  We can use a
Kconfig option like HAS_NEWLIB_LIBC_NANO to convey that this feature is
supported by that toolchain.

We look for the toolchain Kconfig in ${TOOLCHAIN_KCONFIG_DIR}/Kconfig,
and default TOOLCHAIN_KCONFIG_DIR to:

${TOOLCHAIN_ROOT}/cmake/toolchain/${ZEPHYR_TOOLCHAIN_VARIANT})

toolchain specific cmake files can override the default if needed.

Additionally tweaked the zephyr/generic.cmake to use
${CMAKE_CURRENT_LIST_DIR} to reduce some duplication.

Ulf Magnusson 9cdb6f4033 kconfig: Make FLASH_LOAD_OFFSET/SIZE non-configurable when DT is used
Having FLASH_LOAD_OFFSET and FLASH_LOAD_SIZE always configurable froze
their values at 0 when BOOTLOADER_MCUBOOT was enabled in menuconfig,
when instead the values from /chosen/zephyr,code-partition in devicetree
should be used. BOOTLOADER_MCUBOOT selects USE_CODE_PARTITION, which is
a flag to use the devicetree information.

To fix it, only make FLASH_LOAD_OFFSET and FLASH_LOAD_SIZE configurable
when USE_CODE_PARTITION is disabled. It looks like no configuration
files set them at the moment.

See the added documentation in

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

Ulf Magnusson f065eb4271 kconfig: Fix wrong partition size by changing type of FLASH_LOAD_SIZE
FLASH_LOAD_SIZE gets its default from the $(dt_chosen_reg_size)
function, which is defined in scripts/kconfig/kconfigfunctions.py.
$(dt_chosen_reg_size) returns a decimal value rather than a hex value.

Previously, FLASH_LOAD_SIZE was declared as hex, which made Kconfiglib
automatically prepend 0x to its value (the same logic is in the C
Kconfig tools). This gave an incorrect size in .config, e.g.
CONFIG_FLASH_LOAD_SIZE=0x374784 where CONFIG_FLASH_LOAD_SIZE=374784 was
intended.

Fix it by changing the type of FLASH_LOAD_SIZE to int. All other symbols
that use $(dt_node_reg_size) and $(dt_chosen_reg_size) are int too
(FLASH_SIZE and SRAM_SIZE, plus BOOTLOADER_SRAM_SIZE is also int).

This has some subtle breakage potential in that FLASH_LOAD_SIZE has a
prompt (is user-configurable in the menuconfig or by changing .config
files). Nothing seems to directly assign in Zephyr at least.

Andy Ross fe04adf99b lib/os: Conditionally eliminate alloca/VLA usage
MISRA rules (see #9892) forbid alloca() and family, even though those
features can be valuable performance and memory size optimizations
useful to Zephyr.

Introduce a MISRA_SANE kconfig, which when true enables a gcc error
condition whenever a variable length array is used.

When enabled, the mempool code will use a theoretical-maximum array
size on the stack instead of one tailored to the current pool
configuration.

The rbtree code will do similarly, but because the theoretical maximum
is quite a bit larger (236 bytes on 32 bit platforms) the array is
placed into struct rbtree instead so it can live in static data (and
also so I don't have to go and retune all the test stack sizes!).
Current code only uses at most two of these (one in the scheduler when
SCHED_SCALABLE is selected, and one for dynamic kernel objects when
USERSPACE and DYNAMIC_OBJECTS are set).

This tunable is false by default, but is selected in a single test (a
subcase of tests/kernel/common) for coverage.  Note that the I2C and
SPI subsystems contain uncorrected VLAs, so a few platforms need to be
blacklisted with a filter.

As a step to completing removing use of Kconfig defines in dts files we
need to change how we configure/set CONFIG_FLASH_LOAD_{OFFSET,SIZE}.

Previously we would set them based on how the chosen property
'zephyr,code-partition' was set to.  If 'zephyr,code-partition' wasn't
set we would default the values to 0.  We had some generic overlay logic
which would define 'zephyr,code-partition' based on
CONFIG_BOOTLOADER_MCUBOOT.

Going forward if the DTS has 'zephyr,code-partition' set we will
generate DT_CODE_PARTITION_OFFSET & DT_CODE_PARTITION_SIZE defines.  We
will leave it to Kconfig to set CONFIG_FLASH_LOAD_OFFSET &
CONFIG_FLASH_LOAD_SIZE.

We introduce a python script that allows Kconfig to extract data from
the DTS and thus we can utilize DT_CODE_PARTITION_OFFSET and
DT_CODE_PARTITION_SIZE values to set defaults for
CONFIG_FLASH_LOAD_OFFSET & CONFIG_FLASH_LOAD_SIZE.

-DTC_SHIELD_FIXUP
Then, consume these variables when needed.

Shield overlay is conceived as the very first overlay applied
to the board dts. It intends to build a new board that should
then behave as any other board versus common or user's overlay.

Ulf Magnusson d713033d5c Kconfig: Use new preprocessor syntax for env. variables
With the new Kconfig preprocessor (described in
https://github.com/torvalds/linux/blob/master/Documentation/kbuild/
kconfig-macro-language.txt), the syntax for expanding environment
variables is $(FOO) rather than $FOO.

$(FOO) is a general preprocessor variable expansion, which falls back to
environment variables if the variable isn't set (like in Make). It can
also be used in prompts, 'comment's, etc.

The old syntax will probably be supported forever in Kconfiglib for
backwards compatibility, but might as well make it consistent now that
people might start using the preprocessor more.
