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

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

The STM32H7xx HAL LPUART AF macros are missing the number, this HAL is the

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.

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.

The ESP32C3 supports timer source clock APB and XTAL so it does have a

If a CMake-build is run with `make BUILD=/outside/path` then
makeversionheader.py is run with the CWD set to the build directory, which
means the git version lookup will fail and silently fall back to the
mpconfig.h mode (giving the wrong result).
This commit:
- Uses the location of makeversionheader.py to find the repo path.
- Allows overriding this path via --repo-path.

For STM32L4, hardware I2C can be implemented by using TIMINGR.
This commit enables:
- Use of hardware I2C in machine.I2C.
- Specifying a frequency greater than or equal to 400KHz with pyb.I2C.
For STM32L4 series, the internal sensors are connected to:
- ADC1_IN0: Internal voltage reference
- ADC1_IN17: Temperature sensor
- ADC1_IN18: VBAT battery voltage monitoring
but ADC_CHANNEL_VREFINT, ADC_CHANNEL_VBAT, ADC_CHANNEL_TEMPSENSOR are not
defined as 0, 17, 18.
This commit converts channel 0, 17, 18 to ADC_CHANNEL_x in
adc_get_internal_channel().
Prior to this commit, the actual I2C frequency can be faster than specified
one and it may exceed the I2C's specification for Fast Mode. The frequency
of SCL should be less than or equal to 400KHz in Fast Mode.
This commit fixes this issue for F4 MCUs by rounding up the division in the
frequency calculation.
Excuting the code:
i2c = I2C(1, I2C.CONTROLLER, dma=True)
tmp = i2c.recv(1, i2c_addr)
recv_data = bytearray(56)
i2c.recv(recv_data, i2c_addr)
The second i2c.recv() fails with OSError: [Errno 110] ETIMEDOUT. When
receiving greater than or equal to 2 bytes at first i2c.recv(), the second
i2c.recv() succeeds. This issue does not occur without DMA.
Details of change: when executing I2C with DMA:
- Bit 11 of I2Cx_CR2 (DMA Request Enable) should be 1 to indicate that DMA
transfer is enabled. This bit is set after I2C event interrupt is
enabled in HAL_I2C_Master_Transmit_DMA()/HAL_I2C_Master_Receive_DMA(), so
DMA Request Enable bit might be 0 in IRQHandler.
- In case of data receive:
- When only 1 byte receiption, clear I2Cx_CR1's bit 10 (ACK).
- When only 2 byte receiption, clear I2Cx_CR1's bit 10 (ACK) and set
bit 11 (POS).
- When greater than or equal to 2 byte receiption, bit 12 of I2Cx_CR2
(DMA Last Transfer) should set to generate NACK when DMA transfer
completed.
Otherwise, the I2C bus may be busy after received data from peripheral.
Instead of defining `MICROPY_PY_BTREE` in `mpconfigport.h` we can define
it via CMake similar to how other ports that use Makefiles define it in
`mpconfigport.mk`.

If `-march` isn't set then it means the user hasn't thought about it, or in
the case of freezing, MPY_CROSS_FLAGS isn't set. It's almost certainly
going to lead to problems, as there's no reason why the host architecture
is likely to be the right choice.
Compiling regular Python code is unaffected, but if `@native`/`@viper` is
used, the compiler will raise `SyntaxError: invalid arch`.
For situations where you explicitly want to use the host architecture (e.g.
for running tests on the unix port), added -march=host that keeps the old
behavior.
