The register access to SMPR1/SMPR2 was incorrect in three aspects:
1. For channels < 10, SMPR1 was cleared but SMPR2 should have been
cleared
2. The code was not thread-safe
3. An unneeded write was issued. (The compiler won't combine the
in-place bitwise operations into a single read-modify-write
sequence on `volatile` memory.)

This adds mspdebug as package, similar to EDBG, so that the
programmer/debugger is build from source.
This has the advantage that we can indeed provide patches of our own.
The first patch fixes a bug with the CPU detection of `mspdebug` in
combination with the Olimex MSP430-JTAG-TINY-V2. The second adds the
`--expect-id <CPU_NAME>` argument.
The RIOT integration is updated to directly make use of the
`--expect-id` parameter. No more spending time debugging why firmware
the firmware for the `olimex-msp430-h2618` doesn't run when flashed on
the `olimex-msp430h1611` hardware :D
- Test native64 like native in murdock
- Add native64 to "Platform: native" in github labeler
- Add "BUILDTEST_MCU_GROUP == x86_64" to `dist/tools/ci/build_and_test.sh`
Adds a separate board for native64 instead of the `NATIVE_64BIT` workaround.
The files in `boards/native64` are more or less dummy files and just include
the `boards/native` logic (similar to `openlabs-kw41z-mini-256kib`).
The main logic for native is in `makefiles/arch/native.inc.mk`, `cpu/native`
and `boards/native`.
The remaining changes concern the build system, and change native board checks
to native CPU checks to cover both boards.
This allows to define an extra string that will be output as part
of the version command.
e.g. an application may define
RIOT_VERSION_EXTRA += v1.33.7
RIOT_VERSION_EXTRA += flashed by $(shell whoami
This adds two functions:
void gpio_ll_switch_dir_output(gpio_port_t port, uword_t outputs);
void gpio_ll_switch_dir_input(gpio_port_t port, uword_t inputs);
The first configures GPIO pins specified by a bitmask as output, the
second configures the specified pins as input.
The main use case is to allow bit-banging bidirectional protocols using
more basic GPIO peripherals that do not implement open drain mode, such
as found e.g. on MSP430, ATmega, or SAM0.
It is not intended to implement this feature on modern MCUs with
sophisticated GPIO peripherals.
Use analog mode for GPIO_DISCONNECT, as this is said to have the lowest
current leakage due to disabling the Schmitt trigger and correctly
detect this in `gpio_ll_query_conf()`.
Also drop the `schmitt_trigger_disabled` member in `gpio_conf_t`, as
the Schmitt trigger is only ever disabled in Analog mode anyway and
cannot be freely configured.
The separate Schmitt trigger bit in the configuration is dropped, as
the Schmitt trigger is only every disabled when in `GPIO_DISCONNECT`
mode. So no need to encode the same information twice.
The `gpio_state_t` is improved to be a bitmask that holds the
MODER register value and a flag indicating whether open-drain mode
should be enabled.
Finally, `GPIO_DISCONNECT` is implemented. This is done by placing the
GPIO in analog mode, which by disabling the Schmitt trigger reduces
power consumption.
