Like Clang, GCC warns about this file, but only with -Woverride-init
which is enabled by -Wextra. Disable the warnings for this file just
like we do for Clang to make -Wextra happy.
When compiling with -Wextra which includes -Wmissing-field-initializers
GCC will warn that the defval field of mp_arg_val_t is not initialized.
This is just a warning as it is defined to be zero initialized, but since
it is a union it makes sense to be explicit about which member we're
going to use, so add the explicit initializers and get rid of the
warning.
On x86 chars are signed, but we're comparing a char to '0' + unsigned int,
which is promoted to an unsigned int. Let's promote the char to unsigned
before doing the comparison to avoid weird corner cases.
The function scope_find_or_add_id used to take a scope_kind_t enum and
save it in an uint8_t. Saving an enum in a uint8_t is fine, but
everywhere this function is called it is not actually given a
scope_kind_t but an anonymous enum instead. Let's give this enum a name
and use that as the argument type.
This doesn't change the generated code, but is a C type mismatch that
unfortunately doesn't show up unless you enable -Wenum-conversion.
If the device is not connected over USB CDC to a host then all output to
the CDC (eg initial boot messages) is written to the CDC TX buffer with
wrapping, so that the most recent data is retained when the USB CDC is
eventually connected (eg so the REPL banner is displayed upon connection).
This commit fixes a bug in this behaviour, which was likely introduced in
e4fcd216e0, where the initial data in the CDC
TX buffer is repeated multiple times on first connection of the device to
the host.

This is a generally useful feature and because it's part of the object
model it cannot be added at runtime by some loadable Python code, so enable
it on the standard unix build.
The last argument of TUD_CDC_DESCRIPTOR() is the endpoint size (or
wMaxPacketSize), not the CDC RX buffer size (which can be larger than the
endpoint size).

When installing WS firmware, the very first GET_STATE can take several
seconds to respond (especially with the larger binaries like
BLE_stack_full).
Allows stm.rfcore_sys_hci to take an optional timeout, defaulting to
SYS_ACK_TIMEOUT_MS (which is 250ms).

The flash can sometimes be in an already-unlocked state, and attempting to
unlock it again will cause an immediate reset. So make _Flash.unlock()
check FLASH_CR_LOCK to get the current state.
Also fix some magic numbers for FLASH_CR_LOCK AND FLASH_CR_STRT.
The machine.reset() could be removed because it no longer crashes now that
the flash unlock is fixed.

This commit adds a script that can be run on-device to install FUS and WS
binaries from the filesystem. Instructions for use are provided in
the rfcore_firmware.py file.
The commit also removes unneeded functionality from the existing rfcore.py
debug script (and renames it rfcore_debug.py).
The new functions provide FUS/WS status, version and SYS HCI commands:
- stm.rfcore_status()
- stm.rfcore_fw_version(fw_id)
- stm.rfcore_sys_hci(ogf, ocf, cmd)
Changes are:
- Fix missing IRQ handler when SDMMC2 is used instead of SDMMC1 with H7
MCUs.
- Removed outdated H7 series compatibility macros.
- Defined common IRQ handler macro for F4 series.
It requires mp_hal_time_ns() to be provided by a port. This function
allows very accurate absolute timestamps.
Enabled on unix, windows, stm32, esp8266 and esp32.

With a warning that this way of constructing software I2C/SPI is
deprecated. The check and warning will be removed in a future release.
This should help existing code to migrate to the new SoftI2C/SoftSPI types.

Previous commits removed the ability for one I2C/SPI constructor to
construct both software- or hardware-based peripheral instances. Such
construction is now split to explicit soft and non-soft types.
This commit makes both types available in all ports that previously could
create both software and hardware peripherals: machine.I2C and machine.SPI
construct hardware instances, while machine.SoftI2C and machine.SoftSPI
create software instances.
This is a breaking change for use of software-based I2C and SPI. Code that
constructed I2C/SPI peripherals in the following way will need to be
changed:
machine.I2C(-1, ...) -> machine.SoftI2C(...)
machine.I2C(scl=scl, sda=sda) -> machine.SoftI2C(scl=scl, sda=sda)
machine.SPI(-1, ...) -> machine.SoftSPI(...)
machine.SPI(sck=sck, mosi=mosi, miso=miso)
-> machine.SoftSPI(sck=sck, mosi=mosi, miso=miso)
Code which uses machine.I2C and machine.SPI classes to access hardware
peripherals does not need to change.

can no longer delegate to create a hardware-based SPI instance.

Also rename machine_i2c_type to mp_machine_soft_i2c_type. These changes
make it clear that it's a soft-I2C implementation, and match SoftSPI.

Some downstream projects may use tags in their repositories for more than
just designating MicroPython releases. In those cases, the
makeversionhdr.py script would end up using a different tag than intended.
So tell `git describe` to only match tags that look like a MicroPython
version tag, such as `v1.12` or `v2.0`.
Zephyr v2.4.0 added a const qualifier to usages of struct device to
allow storing device driver instances exclusively in flash and thereby
reduce ram footprint.

The use of -S ensures that only the CPython standard library is accessible,
which makes tests run the same regardless of any site-packages that are
installed. It also improves start-up time of CPython, reducing the overall
time spent running the test suite.
tests/basics/containment.py is updated to work around issue with old Python
versions not being able to str-format a dict-keys object, which becomes
apparent when -S is used.
