This adds a new subdirectory called `fuzzing/` which will contain
applications for fuzzing various RIOT network modules in the future.
This subdirectory is heavily inspired by the `examples/` subdirectory.
The fuzzing applications use AFL as a fuzzer. Each application contains
Makefiles, source code, and an input corpus used by AFL to generate
input for fuzzing.
Enabled by the gnrc_netif_events pseudo module. Using an internal event
loop within the gnrc_netif thread eliminates the risk of lost interrupts
and lets ISR events always be handled before any send/receive requests
from other threads are processed.
The events in the event loop is also a potential hook for MAC layers and
other link layer modules which may need to inject and process events
before any external IPC messages are handled.

With #10970 only existing *.c files will be added to SRC when using
the SUBMODULES mechanism, so SUBMODULES_NOFORCE (used to filter out
non existing source files) is now redundant so remove the usage.
'merged.config' may not always be present (e.g. when no files to merge
are present). In order to always have an up-to-date configuration file
'out.config' will be generated mirroring the content of 'autoconf.h'.
This is the file that the build system will include to read the current
configuration symbols.
- Add FEATURES_REQUIRED_ANY to dependency-debug:
Now `make dependency-debug` by default also stores the contents of
`FEATURES_REQUIRED_ANY`.
- makefiles/features_check.inc.mk: Break long lines
- {tests/minimal,tests/unittests,bootloaders/riotboot}:
Disable auto_init_% in addition to auto_init.
This works around weird behavior due to the USEMODULE being recursively expended
in the first iteration of dependency resolution: Modules added to DEFAULT_MODULE
get automatically added to USEMODULE during the first run, but not for
subsequent. This should be iron out later on.
Goals:
- Untangle dependency resolution and feature checking for better maintainability
- Improve performance of "make info-boards-supported"
Changes:
- Makefile.dep
- Dropped handling of default modules and recursion
- Now only dependencies of the current set of used modules and pkgs are
added
==> External recursion is needed to catch transient dependencies
- Changed Makefile.features:
- Dropped checking of provided features
- Dropped populating FEATURES_USED with provided features that are required
or optional
- Dropped populating FEATURES_MISSING with required but not provided
features
- Dropped adding modules implementing used features to USE_MODULE
==> This now only populates FEATURES_PROVIDED, nothing more
- Added makefiles/features_check.inc.mk:
- This performs the population of FEATURES_USED and FEATURES_MISSING now
- Added makefiles/features_modules.inc.mk:
- This performs now the addition of modules implementing used features
- Added makefiles/dependency_resolution.inc.mk:
- This now performs the recursion required to catch transient dependencies
- Also the feature check is performed recursively to handle also required
and optional features of the transient dependencies
- DEFAULT_MODULES are added repeatedly to allow it to be extended based on
used features and modules
==> This allows modules to have optional dependencies, as these
dependencies can be blacklisted
- Use simply expanded variables instead of recursively expended variables
(`foo := $(bar)` instead `foo = $(bar)`) for internal variables during feature
resolution. This improves performance significantly for
`make info-boards-supported`.
- Reduce dependency resolution steps in `make info-boards-supported`
- Globally resolve dependencies without any features (including arch)
provided
==> This results in the common subset of feature requirements and modules
used
- But for individual boards additional modules might be used on top due
to architecture specific dependencies or optional features
- Boards not supporting this subset of commonly required features are not
supported, so no additional dependency resolution is needed for them
- For each board supporting the common set of requirements a complete
dependency resolution is still needed to also catch architecture specific
hacks
- But this resolution is seeded with the common set of dependencies to
speed this up
This adds cortexm_fpu to the DEFAULT_MODULE list when the feature
cortexm_fpu is provided by the architecture. It also moves the
dependency resolution of this module to the architecture-specific
Makefile.dep file.
This moves the following modules to a architecture-specific Makefile.dep
file:
- cortexm_common
- cortexm_common_periph
- newlib
- newlib_nano
- periph
An application/test/module that requires one feature out of a set of
alternatives (let's say either periph_uart, periph_spi, or periph_i2c) can
request this now using:
FEATURES_REQUIRED_ANY += periph_uart|periph_spi|periph_i2c
RFC4648 specifies an alternate alphabet for base64 encoding / decoding
where '+' and '/' are exchanged for '-' and '-' to make the resulting
string safe to use in filenames and URLs.
This adds a base64url_encode() function that uses the alternate alphabet.
The base64_decode() function is extended to accept both alphabets.
This adds a driver for the SPI based AT86RF215 transceiver.
The chip supports the IEEE Std 802.15.4-2015 and IEEE Std 802.15.4g-2012 standard.
This driver supports two versions of the chip:
- AT86RF215: dual sub-GHz & 2.4 GHz radio & baseband
- AT86RF215M: sub-GHz radio & baseband only
Both radios support the following PHY modes:
- MR-FSK
- MR-OFDM
- MR-O-QPKS
- O-QPSK (legacy)
The driver currently only implements support for legacy O-QPSK.
To use both interfaces, add
GNRC_NETIF_NUMOF := 2
to your Makefile.
The transceiver is able to send frames of up to 2047 bytes according to
IEEE 802.15.4g-2012 when operating in non-legacy mode.
Known issues:
- [ ] dBm setting values are bogus
- [ ] Channel spacing for sub-GHz MR-O-QPSK might be wrong
- [ ] TX/RX stress test will lock up the driver on openmote-b
If flasher is changed then make will still see it as a FLASH
dependency and try to execute the target which will likely not
exist.
A use case for this is when flashing on a remote machine and setting
FLASHER=ssh to then execute the FLASHER on the remote.
On NixOS, there is no `/bin/echo`, instead
`which echo` will return
/home/benpicco/.nix-profile/bin/echo
so hard-coding the path will break here.
Use `/usr/bin/env` to get the path of `echo`.
This should be availiable on all systems at the same location.
Declaring all auto_init_% modules as pseudomodules will allow
using auto_init_% modules as modules that can be disabled. This
will give a higher lever of granularity allowing users to not
disable the complete auto_init module but only some of them.
This is used now to set the `DEBUGSSERVER` as the `gdb_agent_console`
file was removed from UniFlash.

- riotboot targets should not be needed for riotboot application
so dont include it.
- also fixes#12003 by not setting FLASHFILE = $(RIOTBOOT_EXTENDED_BIN)
when compiling riotboot application
If CC_NOCOLOR was not set by the user it was set according to the
terminal support of colored output.
But since CC_NOCOLOR is also used to set `-fdiagnostics-color` flags
this means changing `CFLAGS` according to terminal support of colored
output.
This is not needed for `-fdiagnostics-color` since this option is by
default `auto` if the compiler supports colored output, and `auto`
means it will only use color when standard error is a terminal.
In Windows setups using MSYS environment variables which start with a
slash get the 'root path' added. This adds a second slash to the content
of KCONFIG_AUTOHEADER_HEADER, so the first one is escaped when building
on those platforms.
Having the definitions sit in the `net/gnrc/sixlowpan/frag.h` header
does not make much sense, when using Selective Fragment Forwarding
(and the fragmentation buffer already includes a
`net/gnrc/sixlowpan/frag/stats.h` header), so they are moved to their
own header. Since with this change it makes more sense to have the
statistics stored in their own sub-module, the pseudo-module is also
actualized.
This adds a check to decide if Kconfig should run on a build. It will
run if any of the following conditions is true:
- A file with '.config' extension is present in the application folder
- A 'Kconfig' file is present in the application folder
- A previous configuration file is present (e.g. from a previous call to
menuconfig)
- menuconfig is being called
This assumes that Kconfig will not generate any default configurations
just from the Kconfig files outside the application folder (i.e. module
configuration via Kconfig is disabled by default). Should this change,
the check would not longer be valid, and Kconfig would have to run on
every build.
Introduce a new variable 'BOARDSDIR' to use when referencing the base
boards directory.
This is a transition to allow defining external boards while still using
the `RIOT/boards` directory for like `boards/common` for example through
'RIOTBOARD'.
- The autoconf.h header file, generated with the current Kconfig
configurations, is added as a build dependency.
- autoconf.h depends on the proper tool (genconfig) and a Kconfig.dep
which contains the dependencies for the given application and board,
this is generated from $(USEMODULE).
- The menuconfig target is added, to allow the configuration of modules
using the Kconfig system.
When CCACHE_BASEDIR variable is set, ccache rewrites absolute paths into
relative paths before computing the hash that identifies the compilation
for all the paths under that directory.
The problem is that those paths are also used when the compiler is
called, so the generated dependency files (*.d) will have a relative
path to the object files, and thus, it will not match our rule for
compiling (we use absolute paths). As dependency files define the
targets this way, any change on its dependencies (e.g. an included
header file) will not re-trigger a build.
The generic approach of calling avrdude to perform a reset with `make reset`
does also work on board with a bootloader, but only if no other process is
also accessing the serial (e.g. via `make term`). `make test` first accesses
the serial and then performs `make reset` to not miss any output on the serial.
This however blocks when `make reset` also wants to access that serial.
As workaround, `make reset` is no only provided if the ATmega device is not
programmed via bootloader. Normally, those boards reset anyway upon `make term`,
which allows `make test` to work normally again.
The INA219 has the exact same interface as the INA220 (including values and
semantics of the configuration register). Thus, this driver can be used for
both. The ina220 has been renamed to ina2xx to reflect this and pseudo modules
for the ina220 and ina219 have been added.
miniterm.py is a simple terminal program that is included with pyserial.
This means that it is available wherever pyterm can work. It allows raw
access, does line translation and passes through special characters.

Added driver for the WS2812/SK6812 RGB LEDs often sold as NeoPixels, which due
to their integrated RGB controller can be chained to arbitrary length and
controlled with a single GPIO.
For regular modules, adding files to BLOBS is sufficient to create the
corresponding headers.
Application modules are different, as they use a minimal makefile
(makefiles.application.inc.mk) to build, thus application level
variables are not available.
This commit makes Makefile.include pass BLOBS to the application
Makefile as APPLICATION_BLOBS, and application.inc.mk use that variable
as value for BLOBS.
The indirection is necessary so submakefiles (e.g., those visited by
DIRS) do not hard override BLOBS.
In order to flash AVR devices, avrdude needs the ability to reset them:
Those using a bootloader will only enter it after a reset, and those programmed
via ISP also need a reset to enter ISP mode.
Sadly, avrdude has no option to reset the board. But running it without commands
will read and print the boards identification and fuse settings. For this, as
reset is needed. This commit uses this side-effect reset to implement make reset
for all AVR based boards
Clean up `default-channel.inc.mk` to only set the custom CFLAGS
if they are really needed.
This should help avoid cluttering `riotbuild.h`.
The default PAN ID configuration should be just as easy to set
as the default channel, so also add an option for that while we
are at it.
The ATmega128RFA1 and ATmega256RFR2 contain a version of this IP
on the MCU.
The radio core behaves mostly like a at86rf231, but all registers
are mapped to memory and radio states can directly generate interrupts
on the CPU.
The ATmega256RFR2 adds support for automatic retransmissions.
This has not been implemented yet.

- Move serial.inc.mk in mega-xplained/Makefile.include after
PROG_DEV so PROG_DEV can still default to PORT
- Add deprecation warning for arduino-leonardo and mega-xplained
`-Watomic-alignment` warns when C11 atomics have to be implemented via a to one
of the functions in `core/atomic_c11.c`. Unlike to the context of Desktop or
Server class machines, the performance penalty of this calls is insignificant
(and not existing with LTO). So this is not an issue in our context.
On the other hand: Keeping `-Watomic-alignment` prevents building applications
using C11 atomics on all platforms the atomic operations are not implemented
without calls to `core/atomic_c11.c` (due to `-Werror`), reducing portability.
So not only does the warning is not useful in our context, it actually prevents
portable use of C11 atomics. It is the most sensible thing to just disable it.
By ensuring the PORT auto-detection worked, we can give meaningful
error messages and fail earlier.
This uses ensure_value from makefiles/utils/checks.mk. An include was
added to Makefile.include to make this fuction available to all other
makefiles.
This script can detect [Black Magic Probes](https://github.com/blacksphere/blackmagic/wiki) and act as a flashloader (and more).
It is compatible with Linux and macOS.
All important options that can be set via the monitor command are available as arguments.
Makefiles for using `make flash`, `make erase`, `make debug` and `make term` with the script are included.
Remove the workaround for clang 3.6.2 that did not support

clang 3.8 was already supporting it according to the PR introducing the check.
clang >=3.8 is avaible since ubuntu-xenial and debian-stretch.
The current ubuntu-bionic has clang 6 and debian-buster clang 7.
This removes overwriting 'CPU_ARCH'.
Add a 'dependency-debug' and a 'DEPENDENCY_DEBUG=1' option for
'info-boards-supported' to save some variables used when resolving
dependencies.
Print some some 'sorted' variables to simplify comparing the actual value

This should help tracking changes introduced when refactoring the

Microchip offers ready-to-use modules with the mrf24j40 chip.
All but the MRF24J40MA integrate an external PA/LNA, they also come
with an RF shield.
If the PA/LNA is not enabled, the signal off these modules is really
poor.
This adds pseudomodules so that the PA/LNA is automatically enabled
when the appropriate module is used.
Do not remove the '-D' and '-U' values from CFLAGS.
This prevents issues where a '-D' could contain a space.
Some values way be duplicated from the 'riotbuild.h' header and the
command line but with the same value so without conflict.
To not put too many things in the command line, the -DMODULE_NAME are
only put in CFLAGS_WITH_MACROS.
Also, as now, the deferred value of CFLAGS is used for 'riotbuild.h',
macros set after the inclusion of `Makefile.include` will be taken into
account.
This commit overrides the default flash recipe with an edbg specific

pic32prog is a program for flashing pic32 boards from command line on Linux.
It works with:
* Microchip PICkit2
* Microchip PICkit3 with script firmware.
* Other ones: https://github.com/sergev/pic32prog/wiki
Depending on the PROGRAMMER used, the file used for flashing may be
different, like openocd/jlink, so the file being generated when
compiling should be different.
Because of this, when building in docker, the build system needs to know
for which programmer you are building for.
This manifested for 'nordic_softdevice' applications when using 'openocd'
but is not limited to this case.
This adds a new target "archive-check".
Thin archives should be created with relative paths so that archives created
in a build container are useful in the host. This check ensures there are no
absolute paths inside thin archives.
Normal, or thick archives contain a copy of the object code. Thin
archives, on the contrary, are just an index to the .o files.
This patch does two things:
1. Change ARFLAGS to enable the "T" options.
2. Call AR with all relative paths.
The second step is necessary because the build system handles all
absolute paths. If the index in the thin archive contains absolute
paths, archives created in docker are no usable outside, and moving
the objects breaks the archive.
If all arguments to AR are relative, the resulting archive contains
filenames *relative to the .a file* and nothing should break as long
as the relative location of the .a and .o remains unchanged.
Compilation time is unchanged, but disc usage is reduced by approximately
50%. These are the result of a full RIOT build:
| Thin Archive | no | yes | Savings (%) |
| -------------- | ------: | ----: | ----------- |
| pkg (10e6 KiB) | 1 790 | 905 | 49% |
| Non pkg | 71 | 71 | 1% |
| Total | 1 812 | 976 | 46 % |
The default channel configuration is managed within the Makefiles of many
examples and tests. This commit moves the default channel logic to
`makefiles/default-channel.ink.mk` to ease maintenance. All Makefiles that
previously managed the default channel configuration themself have been

The default channel configuration of the cc110x has been added
Use the -gz option to compress ELF sections containing DWARF information.
This saves around 50% of disk space, without any side effects.
See https://gcc.gnu.org/onlinedocs/gcc-9.2.0/gcc/Debugging-Options.html#Debugging-Options
for more infomation on this option.
Some platforms have an outdated toolchain that does not support -gz so
the flag is blacklisted there. Even then, the results are quite impressive.
I used @cladmi's `buildtest` branch (https://github.com/cladmi/RIOT/tree/wip/du/buildtest)
with this change and compiled the `examples/default` application:
```
$ BUILD_IN_DOCKER=1 DOCKER="sudo docker" make -C examples/default buildtest-indocker
```
The size was obtained with:
```
$ find output -name "*.bin.bindirsize" -type f -exec tail -n1 '{}' \; | cut -f 1 | awk '{s+=$1} END {printf "%.0f", s}'
```
Results:
- Vanilla: 10328112 KB (~10GB).
- with -gz: 4982788 KB (~5GB).
This was inspired by #8496.
The current code for detecting whether colors should be used by default
was not working. Normally what programs such as git or grep do is check
if they are writing to a pipe.
To see the issue by yourself:
$ BOARD=samr21-xpro make -C tests/periph_qdec > I_SHOULD_NOT_HAVE_COLORS 2>&1
This commit uses MAKE_TERMOUT, MAKE_TERMERR and if ANY of them is NOT
a terminal, colors are disabled.
Update the optional flags to use 'OPTIONAL_CFLAGS' instead of evaluating
everytime.
They are now blacklisted by architecture/toolchain according to the
current docker reference image.
Handle declaring OPTIONAL_CFLAGS and blacklisting them with
OPTIONAL_CFLAGS_BLACKLIST.
This should replace checking everytime if options are supported.
Add make only function to convert strings to lowercase and uppercase.
This can replace the `$(shell echo $(var) | tr 'a-z-' 'A-Z_')` pattern.
Using the 'make' implementation results in being around 100 times faster.
CFLAGS_CPU is required for 'pkg/openthread'. So declare it as a global
compilation variable.
The goal is to move the export to `makefiles/vars.inc.mk` and remove the
local exports that could be in boards/cpu/arch.
Add a variable for `pyterm` specific flags that are not handled by other
terminals.
This will prevent issues with boards that have options only supported by
`pyterm` and setting `pyterm` options from the environment.

The value must be saved from the original value to allow restoring it.
This has currently no impact on 'info-boards-supported' as it is
currently ignored.
By default if a test is available and not blacklisted it will be run by
murdock.
This will move from a whitelisting everything that works, to
blacklisting what fails. This way, failing tests will be easier to
track instead of being silently just not run.
It could even allow introducing failing tests before a fix is available.
Only set `TEST_ON_CI_ENABLED` if the application has tests.
Currently `TEST_ON_CI_WHITELIST` was only set if there were tests.
This is a pre-step to have `TEST_ON_CI_WHITELIST` being `all` by
default.
The cc110x driver has been re-written from scratch to overcome the limitations
of the old driver. The main motivation of the rewrite was to achieve better
maintainability by a detailed documentation, reduce the complexity and the
overhead of the SPI communication with the device, and to allow to
simultaneously use transceivers with different configuration regarding the used
base band, the channel bandwidth, the modulation rate, and the channel map.
Features of this driver include:
- Support for the CC1100, CC1101, and the CC1100e sub-gigahertz transceivers.
- Detailed documentation of every aspect of this driver.
- An easy to use configuration API that allows setting the transceiver
configuration (modulation rate, channel bandwidth, base frequency) and the
channel map.
- Fast channel hopping by pre-calibration of the channels during device
configuration (so that no calibration is needed during hopping).
- Simplified SPI communication: Only during start-up the MCU has to wait
for the transceiver to be ready (for the power regulators and the crystal
to stabilize). The old driver did this for every SPI transfer, which
resulted in complex communication code. This driver will wait on start up
for the transceiver to power up and then use RIOT's SPI API like every other
driver. (Not only the data sheet states that this is fine, it also proved to
be reliable in practise.)
- Greatly reduced latency: The RTT on the old driver (@150 kbps data rate) was
about 16ms, the new driver (@250 kbps data rate) has as RTT of ~3ms
(depending on SPI clock and on CPU performance) (measured with ping6).
- Increased reliability: The preamble size and the sync word size have been
doubled compared to the old driver (preamble: 8 bytes instead of 4,
sync word: 4 byte instead of 2). The new values are the once recommended by
the data sheet for reliable communication.
- Basic diagnostic during driver initialization to detect common issues as
SPI communication issues and GDO pin configuration/wiring issues.
- TX power configuration with netdev_driver_t::set() API-integration
- Calls to netdev_driver_t::send() block until the transmission has completed
to ease the use of the API (implemented without busy waiting, so that the
MCU can enter lower power states or other threads can be executed).
This allows passing other arguments as environment variables in
DOCKER_ENVIRONMENT_CMDLINE and as command line override in
DOCKER_OVERRIDE_CMDLINE without using the automatic detection.
This will allow passing USEMODULE to docker as its value is usually set
in an application Makefile so has its origin changed.
This allows setting other variables that should be exported to the
docker build.
As for other variables, they must still be unmodified before parsing
`docker.inc.mk` to be exported.
The value must be saved from the original value to allow restoring it.
This has currently no impact as 'makefiles/defaultmodules.inc.mk'
and 'DISABLE_MODULE' are ignored in this parsing.
This remove executing buildtest `for` loop in docker.
When building completely in docker, 'buildtest' would hide issues when
the host toolchain would be used when doing `make all` directly.
It has the consequence that it now starts a container for each
compilation which is slower.
The previous behavior can be reproduced by using
BUILD_IN_DOCKER=1 make buildtest-indocker
A side effect is also that now `BUILDTEST_MAKE_REDIRECT` would work when
doing `buildtest` with docker.
Add a 'buildtest-indocker' that forces executing 'buildtest' for loop
completely inside the container.
It prevents starting one container per compilation wich is slower but
it could hide errors where the host toolchain would be used
It is currently equivalent to `buildtest` but will change when the
`buidtest` handling will be move outside of `BUILD_IN_DOCKER`.
Display an error when executed without BUILD_IN_DOCKER=1.
Move git version evaluation to a separate file.
The definition has been updated it to a deferred only definition.
This way git is not called when GIT_VERSION is not used.
Document `BINFILE` in the same ways as `HEXFILE`.
The file does not need to be exported so no reason to do it though.
It also adds it in the `info-build` output in the same way as `HEXFILE`.
Previously, this was hard-coded to allow one file, hard-coded to be
called "flash file".
This commit allows multiple files to be specified via adding them to the
TEST_EXTRA_FILES variable. All files will be stored in the worker's
application bin directory.
Also, the existence check has been removed, as dwqc bails out on missing
file anyways.
... if the riotboot feature is used.
Previously, even an application that had "FEATURES_REQUIRED += riotboot"
set would still flash the non-riotboot binary on "make flash".
This is usualy not what the user wants.
This commit set's the FLASHFILE variable to the combined "riotboot
bootloader + slot0 + empty slot1" binary. This has the effect that make
all, flash and flash-only will compile and/or flash a working riotboot
setup.
tests/riotboot and tests/riotboot_flashwrite now default to flashing the
riotboot-extended binary. tests/riotboot was previously configured to
use the riotboot-combined binary. This has been changed in order to not
behave differently than how usual riotboot applications do.
Introduce a variable to set that a test is blacklisted.
This is a move toward enabling tests by default and adding a blacklisting
reason instead for a board instead of not whitelisting them which hides
the problem.
Currently, a test should be both whitelisted and blacklisted at the same
time to have a meaning. It is planned to whitelist all by default in
an upcoming pull request.
Refactor the handling to use a variable to store if a test is enabled.
Add a 'test-on-ci-enabled' target that test if the test on ci is enabled.
This is a first commit before changing the behavior.
Currently sam0 will always use OpenOCD, even when the JLink programmer is selected.
Instead, use JLinkExe when it's availiable and a J-Link programmer is used.
Evaluate BOARDS only once before going in all directories.
This uses the target specific 'export BOARDS ?=' to export the variable
with its value without evaluating during parsing.
* Add a variable to list all boards without using 'find'.
* By default 'BOARDS' is the list of all boards.
* Add the 'info-boards' target that lists BOARDS.
* Use in RIOT/Makefile
This variable is only used for the term recipe (and maybe for flashing). They
should not be evaluated if they are not needed and the user should not see a
warning that the port is not set if he does not use port (for example in make
all.)
Rational: the periph_common module is required by (most) other periph drivers
and also during startup of the CPU/MCU to run periph_init. The latter is only
required if other periph drivers are used, hence periph_common should be a
depency of periph_* modules and *not* of the CPU/MCU. This PR fixes that
by making periph_common a depency of periph_* and removing the explicit
include in the CPU/MCU implementation.
Put the definition of `FEATURES_USED` in common and use the variable
instead of duplicating code.
This required defining 'FEATURES_OPTIONAL_ONLY|USED' to not overwrite
the value of 'FEATURES_OPTIONAL' as was done before.
Also add 'FEATURES_OPTIONAL_MISSING' to list optional features that were
not included as not provided.
This removes the need to print FEATURES_MISSING with the optional
features too.
Update the FEATURES_OPTIONAL meaning to be more in line since
FEATURES_USED is defined. Handle FEATURES_OPTIONAL as a configuration from
the BSP/build that should not be changed anymore after.
`FEATURES_OPTIONAL` are by definition optional so are not supposed to
cause a build to fail.
Only the 'REQUIRED' ones that are not 'PROVIDED' are 'MISSING'.
* Do not change FEATURES_OPTIONAL to remove REQUIRED features
* Prepare for having a different variable for the previous value
* Update dependency resolution/info-build as FEATURES_OPTIONAL cannot be missing
When '$(PREFIX)objdump' is not present fallback to native '(g)objdump'.
'objdump' is used when flashing for some boards but the toolchain may
not be installed when building in docker.
This will allow using 'objdump' in 'cpu/kinetis/dist/check-fcfield.sh'.
To read float number from stdin, add "-u scanf_float"

`git show --stat` reports `55 insertions(+), 55 deletions(-)`
Which is the same amount as lines that where matching
`export[[:blank::]]\+VARIABLE`.
RESET and RESET_FLAGS are evaluated by the main Makefile.include or by file
included by it. Their value does not need to be exported.
This will also prevent evaluating 'PORT' for RESET_FLAGS when not needed.

This will allow sharing it between Makefile.include and
makefiles/info-global.inc.mk.
Also some common variables definition can also be moved to here.
Part of moving CPU/CPU_MODEL definition to Makefile.features to have it
available before Makefile.include.
This enables "BUILD_IN_DOCKER=1 BOARDS='foo bar' make buildtest".
Without this line, when executed with BUILD_IN_DOCKER, "make buildtest"
would always build all boards.
Add a trivial shell program that scans for all slaves on an I2C bus by iterating
all of the possible 127 I2C addresses and checking for the ACK of the device.
The build system contains several instances of
INCLUDES += -I$(RIOTBASE)/sys/posix/include
This is bypassing the module management system, by directly accesing
headers without depending on a module. The module is the posix module.
That line is also added when one of the posix_* modules is requested.
According to the docs, the posix module provides headers only, but in
reality there is also inet.c.
This patch:
- Moves `inet.c` into `posix_inet`, leaving `posix` as a headers-only
module.
- Rename `posix` as `posix_headers` to make it clear the module only
includes headers.
- Makes `posix_*` modules depend on `posix_headers`, thus removing the
explicit `INCLUDES+=...` in `sys/Makefile.include`.
- Ocurrences of `INCLUDES+=...` are replaced by an explicit dependency
on `posix_headers`.
In UniFlash 4.4.0 the directory where 'xds110reset' is changed.
Try to use the newest one available. If none is found in UNIFLASH_PATH,
try to use one from the PATH to be sure to have a value.

Linkerscript for `nrf52dk` has been updated to use `cortexm.ld` so does
not need the configuration anymore for the removed
`cpu/nrf52/ldscripts/nrf52832xxaa.ld`.
