- Boards using stm32f103xx use the same custom config for xtimer
which relies on the same underlying hardware timers that hang
when sleeping for <20us so spin when approaching that limit.
A new blue pill variant with only 32 KiB of flash (secretly coming with
64 KiB flash) instead of the use 64 KiB flash (secretly coming with 128 KiB)
is not compatible with `make flash`. This commit changes the OpenOCD config
so that both variants can be flashed.
The softdevice is only verified to be working on nrf52832-based
boards. This feature prevents the softdevice from being build for
other, similar targets (e.g. nrf52840-based boards).
Introduce and use a common/remote/Makefile.features.
The boards were already using the common `Makefile.include` and
`Makefile.dep`.
This makes 'include $(RIOTCPU)/cc2538/Makefile.features' be done in
the same module where 'CPU' is defined.
Preparation for moving 'CPU' definition to Makefile.features.
Introduce and use a common/msba2/Makefile.features.
The boards were already using the common `Makefile.include` and

Moved SPI config from boards/common/nrf52xxxdk/include/periph_config.h to
boards/common/nrf52/include/cfg_spi_default.h. This allows all nRF52 based
boards to use this SPI config if applicable and also allows nRF52*-DK boards
to use custom SPI configs, if needed.
PORT_LINUX and PORT_DARWIN are evaluated by
`makefiles/tools/serial.inc.mk` and some boards Makefile.include.
Their value does not need to be exported.
This also globally removes the line saying that the exports are needed
for flash rule.
Keep the compiled '.bin' file to remove the need to compile it when
flashing. This remove the need to have the toolchain when flashing so
allow compiling and flashing with `BUILD_IN_DOCKER=1` without a local
toolchain.
Even if it ends up storing a binary, the file is only 34 bytes.
MSPDEBUGFLAGS is evaluated only in the same file.
Its value does not need to be exported.
This will also prevent evaluating 'PORT' for MSPDEBUGFLAGS when not needed.
DEBUGGER/DEBUGGER_FLAGS/DEBUGSERVER/DEBUGSERVER_FLAGS are evaluated by the
main Makefile.include or by file included by it.
Their value does not need to be exported.
Testing
-------
`git diff --word-diff` only reports `export` being removed.
`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.
Testing
-------
`git diff --word-diff` only reports `export` being removed.
`git show --stat` reports `24 insertions(+), 24 deletions(-)`
Which is the same amount as lines that where matching
`export[[:blank::]]\+VARIABLE`.
FLASHER and FFLAGS 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 FFLAGS when not needed.
Testing
-------
`git diff --word-diff` only reports `export` being removed.
`git show --stat` reports `84 insertions(+), 84 deletions(-)`
Which is the same amount as lines that where matching
`export[[:blank::]]\+VARIABLE`.
The currently supported SAM0 MCUs (samd21, saml21, saml1x) share the same
Timer peripheral, yet each of them carries it's own copy of the Timer
driver.
This introduces a new timer driver that is common for all sam0 MCUs and
uses structs for configuration instead of defines.
UART devices are now configured using static array in header files instead of static variables in implementation to be able to define UART_NUMOF using the size of the array instead of a variable.
SPI devices are now configured using static array in header files instead of static variables in implementation to be able to define SPI_NUMOF using the size of the array instead of a variable.
I2C devices are now configured using static array in header files instead of static variables in implementation to be able to define I2C_NUMOF using the size of the array instead of a variable.
DAC pins are now configured using static arrays in header files instead of static variables in implementation to be able to define DAC_NUMOF using the size of these arrays instead of a variable.
ADC pins are now configured using static arrays in header files instead of static variables in implementation to be able to define ADC_NUMOF using the size of these arrays instead of a variable.
Moving atmega_stdio_init() to cpu_init() just before periph_init() guarantees
that stdio is available to allow DEBUG() in periph_init(). This also helps to
unify the boot up process of ATmega boards and de-duplicates the stdio init from
board_init().
Added file with clock settings for STM32-F7 CPUs with a core clock of 216MHz,
an external high speed clock of 8 MHz and external low speed clock (32.768kHz)
enabled.
Add a rule to build `lpc2k_pgm` when flashing.
It is only compiled if it is using the one in `tools`.
If overwritten to `lpc2k_pgm` if it should be taken from the path,
it is not compiled.
The compilation is still done in `boards/common/msba2/tools` as it was
the case before and this commit does not address this.
Add motor_driver driver configuration example.
The most simple motor driver type is used here (MOTOR_DRIVER_1_DIR) which
needs only one pin to work.
This example uses already configured PWM channels and 2 free GPIOS.

A common configuration file is introduced for stm32f4 with core clock
at 168MHz with HSE at 8MHz, 2 configuration files are introduced to²:
distinguish between clock configuration with and without LSE.
