Consistently use
config FOO
bool/int/hex/string "Prompt text"
instead of
config FOO
bool/int/hex/string
prompt "Prompt text"
(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).
The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.
Most of the grunt work was done by a modified version of

Up until now, Zephyr has patched Kconfig to use the last 'default' with
a satisfied condition, instead of the first one. I'm not sure why the
patch was added (it predates Kconfiglib), but I suspect it's related to
Kconfig.defconfig files.
There are at least three problems with the patch:
1. It's inconsistent with how Kconfig works in other projects, which
might confuse newcomers.
2. Due to oversights, earlier 'range' properties are still preferred,
as well as earlier 'default' properties on choices.
In addition to being inconsistent, this makes it impossible to
override 'range' properties and choice 'default' properties if the
base definition of the symbol/choice already has 'range'/'default'
properties.
I've seen errors caused by the inconsistency, and I suspect there
are more.
3. A fork of Kconfiglib that adds the patch needs to be maintained.
Get rid of the patch and go back to standard Kconfig behavior, as
follows:
1. Include the Kconfig.defconfig files first instead of last in
Kconfig.zephyr.
2. Include boards/Kconfig and arch/<arch>/Kconfig first instead of
last in arch/Kconfig.
3. Include arch/<arch>/soc/*/Kconfig first instead of last in
arch/<arch>/Kconfig.
4. Swap a few other 'source's to preserve behavior for some scattered
symbols with multiple definitions.
Swap 'source's in some no-op cases too, where it might match the
intent.
5. Reverse the defaults on symbol definitions that have more than one
default.
Skip defaults that are mutually exclusive, e.g. where each default
has an 'if <some board>' condition. They are already safe.
6. Remove the prefer-later-defaults patch from Kconfiglib.
Testing was done with a Python script that lists all Kconfig
symbols/choices with multiple defaults, along with a whitelist of fixed
symbols. The script also verifies that there are no "unreachable"
defaults hidden by defaults without conditions
As an additional test, zephyr/.config was generated before and after the
change for several samples and checked to be identical (after sorting).
This commit includes some default-related cleanups as well:
- Simplify some symbol definitions, e.g. where a default has 'if FOO'
when the symbol already has 'depends on FOO'.
- Remove some redundant 'default ""' for string symbols. This is the
implicit default.
Piggyback fixes for swapped ranges on BT_L2CAP_RX_MTU and
BT_L2CAP_TX_MTU (caused by confusing inconsistency).
Piggyback some fixes for style nits too, e.g. unindented help texts.

- Remove redundant 'n' defaults. 'n' is the default value for bool
symbols.
This makes the auto-generated documentation clearer as well: You get

"- n if <propagated dependencies>".

Bool symbols implicitly default to 'n'.

Zephyr currently allows users to choose a compiler optimization
between -O0, -Og and -Os, the default being the latter as it offers a
good compromise between speed and flash usage. In cases the speed
matters and/or the flash usage doesn't, optimizing for speed with -O2
is another alternative. For example in case of a simple application
doing cryptographic signature validation with mbedtls, the flash size
increase by about 15% compared to -Os, while it provides a 15% speed
boost for a RSA signature and 30% speed boost for a ECC signature.
This patches therefore adds a new option CONFIG_SPEED_OPTIMIZATIONS
corresponding to the -O2 flag, but keep the default set to
CONFIG_SIZE_OPTIMIZATIONS.

The various macros to do checks in system call handlers all
implictly would generate a kernel oops if a check failed.
This is undesirable for a few reasons:
* System call handlers that acquire resources in the handler
have no good recourse for cleanup if a check fails.
* In some cases we may want to propagate a return value back
to the caller instead of just killing the calling thread,
even though the base API doesn't do these checks.
These macros now all return a value, if nonzero is returned
the check failed. K_OOPS() now wraps these calls to generate
a kernel oops.
At the moment, the policy for all APIs has not changed. They
still all oops upon a failed check/
The macros now use the Z_ notation for private APIs.

We are using the CMake command 'file(STRINGS' (which defaults to only
decoding ASCII) to read Kconfig configurations. When UTF-8 characters
are detected they are treated as newlines.
This behaviour has caused issues when users have input UTF-8
characters into Kconfig values. E.g. USB device descriptor strings.
This commit adds the flag 'ENCODING "UTF-8"' to the 'file(STRINGS'
command so that UTF-8 characters are correctly passed through the
build system.

This patch does several things, most notably it changes the semantics
of CONFIG_DEBUG. CONFIG_DEBUG continues to behave as a vaguely defined
"debug mode" that enables printf's, -Og, etc. but now the user may
choose to be in "debug mode" while using a different optimization
level than -Og.
Tp support this a new config is defined to enable -Og;
CONFIG_DEBUG_OPTIMIZATIONS.
Additionally CONFIG_SIZE_OPTIMIZATIONS is introduced to allow the user
to explicitly request optimizing for size instead of relying on
defaulting to it.
The three config's {NO,SIZE,DEBUG}_OPTIMIZATIONS are now organized in
a Kconfig choice to ensure that at most one can be enabled at a time.
Finally, selected users of CONFIG_DEBUG have been ported to use one of
the optimizations configs when it was clear from usage that the
intention was to behave differently when using a different
optimization level and not when in "debug mode".

Pass the --print-memory-usage to the linker on the first link if the
toolchain supports it.
Don't use this option with the second link because seeing it twice
could confuse users and using it on the second link would suppress it
when the first link has a ram/flash-usage issue.
Note that the memory regions are symbolic concepts defined by the
linker scripts and do not necessarily map directly to the real
physical address space. Take also note that some platforms do two
passes of the linker so the results do not match exactly to the final
elf file. See also rom_report, ram_report and
https://sourceware.org/binutils/docs/ld/MEMORY.html
This is particularly useful when the linker fails due to excessive
flash/ram usage. When a section does not fit into a memory region the
linker will exit with an error code and will state how big the
overflow was. But it doesn't state what the memory region size is, or
what memory regions exist, which is good to know when debugging
overflow issues.

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make
