This adds a concurrency section to all github workflows to cancel any
in progress workflow when a branch is updated. This should cancel any
ongoing or queued workflows, e.g. when a pull request is updated.

The compiler is not picky right now, but these are actually all syntax
errors:
- await is only valid in an async function
- async functions that use yield are actually async generators (a construct
not supported by the compiler right now)
ADC: The argument of vref=num is an integer. Values for num are:
SAMD21:
0 INT1V 1.0V voltage reference
1 INTVCC0 1/1.48 Analog voltage supply
2 INTVCC1 1/2 Analog voltage supply (only for VDDANA > 2.0V)
3 VREFA External reference
4 VREFB External reference
SAMD51:
0 INTREF internal bandgap reference
1 INTVCC1 Analog voltage supply
2 INTVCC0 1/2 Analog voltage supply (only for VDDANA > 2.0v)
3 AREFA External reference A
4 AREFB External reference B
5 AREFC External reference C (ADC1 only)
DAC: The argument of vref=num is an integer. Suitable values:
SAMD21:
0 INT1V Internal voltage reference
1 VDDANA Analog voltage supply
2 VREFA External reference
SAMD51:
0 INTREF Internal bandgap reference
1 VDDANA Analog voltage supply
2 VREFAU Unbuffered external voltage reference (not buffered in DAC)
4 VREFAB Buffered external voltage reference (buffered in DAC).
Changes in this commit:
- Do not deinit IRQ when uart.deinit() is called with an inactive object.
- Remove using it for the finaliser. There is another machanism for soft
reset, and it is not needed otherwise.
- Do not tag the UART buffers with MP_STATE_PORT, it is not required.
Clearing the DRE flag for the transmit interrupt at the end of a
uart.write() also cleared the RXC flag disabling the receive interrupt.
This commit also changes the flag set/clear mechanism in the driver for SPI
as well, even if it did not cause a problem there. But at least it saves a
few bytes of code.
Applies to both SPI and I2C. The underflow caused high baudrate settings
resulting in the lowest possible baudrate. The overflow resulted in
erratic baudrates, not just the lowest possible.
The datasheet on page 55 shows PF0 (SDA) and PF1 (SCL) are the pins for
I2C2, but these pins do not work. Checking the MBED pinout for the
NUCLEO-F429ZI shows:
I2C1: PB8 (SCL) and PB9 (SDA).
I2C2: PB10 (SCL) and PB11 (SDA).
Both of these work and can be scanned and find devices connected to them.

This changes the signatures of QSPI write_cmd_data, write_cmd_addr_data and
read_cmd_qaddr_qdata so they return an error code. The softqspi and stm32
hardware qspi driver are updated to follow this new signature. Also the
spiflash driver is updated to use these new return values.

Prior to this fix the follow crash occurred. With a GC layout of:
GC layout:
alloc table at 0x3fd80428, length 32001 bytes, 128004 blocks
finaliser table at 0x3fd88129, length 16001 bytes, 128008 blocks
pool at 0x3fd8bfc0, length 2048064 bytes, 128004 blocks
Block 128003 is an AT_HEAD and eventually is passed to gc_mark_subtree.
This causes gc_mark_subtree to call ATB_GET_KIND(128004). When block 1 is
created with a finaliser, the first byte of the finaliser table becomes
0x2, but ATB_GET_KIND(128004) reads these bits as AT_TAIL, and then
gc_mark_subtree references past the end of the heap, which happened to be
past the end of PSRAM on the esp32-s2.
The fix in this commit is to ensure there is a one-byte gap after the ATB
filled permanently with AT_FREE.
Fixes issue #7116.

When you want to use the valgrind memory analysis tool on MicroPython, you
can arrange to define MICROPY_DEBUG_VALGRIND to enable use of special
valgrind macros. For now, this only fixes `gc_get_ptr` so that it never
emits the diagnostic "Conditional jump or move depends on uninitialised
value(s)".

This change makes it so the compiler and persistent code loader take a
mp_compiled_module_t* as their last argument, instead of returning this
struct. This eliminates a duplicate context variable for all callers of
these functions (because the context is now stored in the
mp_compiled_module_t by the caller), and also eliminates any confusion
about which context to use after the mp_compile_to_raw_code or
mp_raw_code_load function returns (because there is now only one context,
that stored in mp_compiled_module_t.context).
Reduces code size by 16 bytes on ARM Cortex-based ports.

This fixes the case for the code size comment action where there is no
matching artifact. Apparently, the result of the github-script action was
not treating `false` as a boolean value. To fix the problem we change the
result to use string. Also add some logging to make the step a bit less
cryptic.

The STM32H7xx HAL LPUART AF macros are missing the number, this HAL is the
only one that's inconsistent in the way it defines LPUART AF macros, so we
only need to define them for H7.
Prior to this commit, only sector 0 was erase/write protected, which may
not be enough to protect all of mboot (especially if mboot lives at a
higher address than the start of flash).
This commit makes sure all internal flash sectors that mboot lives in are
protected from erasing and writing. The linker script must define
_mboot_writable_flash_start for this to work.

This changes the code size workflow to post a comment on pull requests with
the code size report. It also removes the error threshold so that the test
won't fail if code size increases.
Allowable code size changes are subjective, so shouldn't cause CI to fail.
In addition, failing CI tests can cause other hooks like code coverage
reports to be suppressed, so this fixes that problem as well.
Fixes issue #8464.

The code was already checking for duplicate kwargs for named parameters but
if `**kwargs` was given as a parameter, it did not check for multiples of
the same argument name.
This fixes the issue by adding an addition test to catch duplicates and
adds a test to exercise the code.
Fixes issue #10083.

On MacOS and Windows there are a few default serial devices that are
returned by `serial.tools.list_ports.comports()`. For example on MacOS:
```

'device': '/dev/cu.Bluetooth-Incoming-Port',
'hwid': 'n/a',
'interface': None,
'location': None,
'manufacturer': None,
'name': 'cu.Bluetooth-Incoming-Port',
'pid': None,
'product': None,
'serial_number': None,
'vid': None}
{'description': 'n/a',
'device': '/dev/cu.wlan-debug',
'hwid': 'n/a',
'interface': None,
'location': None,
'manufacturer': None,
'name': 'cu.wlan-debug',

Users of mpremote most likely do not want to connect to these ports. It
would be desirable if mpremote did not select this ports when using the
auto connect behavior. These serial ports do not have USB VID or PID
values and serial ports for Micropython boards with FTDI/serial-to-USB
adapter or native USB CDC/ACM support do.
Check for the presence of a USB VID / PID int value when selecting a
serial port to auto connect to. All serial ports will still be listed by
the `list` command and can still be selected by name when connecting.
