To clear wakeup interrupt flag, set CWUTF on RTC_SCR instead of RTC_MISR.

ddf1a383ca stm32/machine_adc: Fix machine.ADC so it works on STM32G0.
Fixes are:
- Enable VREG before initializing ADC.
- The channel value of internal sensor should convert with
  __LL_ADC_CHANNEL_TO_DECIMAL_NB().

7ba82219f3 stm32/adc: Fix pyb.ADC issue for STM32G0.
Fixes are:
- The internal sensors of STM32G0 are connected channel 12, 13, 14.
- Update adc_refcor before reading vbat and tempsensor because reference
  values are at VDDA=3.0V.
- The method of initialize of sampling time is different with other MCUs:
  STM32G0 should initialize SamplingTimeCommon1/2 first.  When reading
  value from ADC, ADC_ChannelConfTypeDef.SamplingTime should be specified
  SamplingTimeCommon1 or SamplingTimeCommon2.  In this patch,
  SamplingTimeCommon2 is used for internal sensors and SamplingTimeCommon1
  is used for external ADC channels.

592affce3f stm32/make-stmconst.py: Fix missing peripheral consts in stm module.
Lines like the following were not handled by `make-stmconst.py`:

    #define APBPERIPH_BASE        (PERIPH_BASE)

This leads to missing definitions on stm module.  For example, `stm.RTC` is
not defined if `RTC_BASE` is defined as

    #define RTC_BASE              (APBPERIPH_BASE + 0x00002800UL)

because `APBPERIPH_BASE` is not handled as a valid id.

This patch modifies the RegExp so it can handle the above.

8c389db6ea unix/main: Ensure atexit function is called with -m <module>.
Previously, when running `micropython -m <module>` and the module called
sys.exit(), the registered atexit function was not executed. This was due
to sys.exit() raising a SystemExit exception, which bypassed the atexit
handler. This change fixes the issue so that the atexit function is
properly invoked when exiting via sys.exit().

Additionally, following the pattern in execute_from_lexer(),
mp_hal_set_interrupt_char() and mp_handle_pending() handling were added to
ensure that the atexit function is also executed when the user exits via
Ctrl-C.

cf097932a2 unix/modsocket: Set file descriptor to -1 on close.
After s.close(), s.fileno() now returns -1, matching CPython behavior.
Some code relies on this compatibility, as it allows checking whether
a socket is closed by testing its fileno() value. This change ensures
better interoperability with existing Python code and libraries.

This adds a QEMU-based bare metal RISC-V 64 bits port.  For the time being
only QEMU's "virt" 64 bits board is supported, using the lp64 ABI and the
RV64IMC architecture.

The port's README is also updated to keep track of these changes.

UART prescaler value should set up correctly to initialize LPUART with low
baudrate for STM32G0/G4/H5.  This can be implemented similarly to

a69425b533 unix/Makefile: Add additional testing targets.
These are convenience targets for running specific tests as a developer.
They are more useful that invoking run-tests directly as they take account
of the VARIANT= specified on the make command-line.

For instance, you can run all tests matching the regular expression "int"
with `make VARIANT=... test//int`.

The new targets are all documented in README.md.

f0c6f16b9e all: Remove Python 2.7 support.
Python 2.7 has been EOL since January 2020.

Ubuntu oldoldlts (Focal Fossa, 20.04) has Python 3.8.  Debian oldoldstable
(Buster, from 2019) has Python 3.7.  RHEL 8 (from 2019) has Python 3.6.

It's easier than ever to install a modern Python using uv.

Given this, it seems like a fine idea to drop Python 2.7 support.

Even though the build is not tested on Python as old as 3.3, I left
comments stating that "3.3+" is the baseline Python version.  However, it
might make sense to bump this to e.g., 3.10, the oldest Python 3 version
used during CI. Or, using uv or another method actually test on the oldest
Python interpreter that is desirable to support (uv goes back to Python 3.7
easily; in October 2025, the oldest supported Python interpreter version
will be 3.10)

371db85c8e esp32/machine_uart: Convert machine.UART objects to static instances.
Makes machine.UART objects static instances (similar to other ports), adds
machine_uart_deinit_all() function for cleanup on soft reset.

- Fixes the case where the OS-level uart_event_task is leaked
  (along with 2KB of heap) when a UART object is garbage collected
  (including after a soft reset).

- Fixes hard fault if a previous UART irq() fires after the UART object is
  garbage collected (including after a soft reset), but before any new UART
  object is instantiated for the same UART number.

- Constructing multiple UART objects for the same UART now returns the
  same instance multiple times, not different instances.

- Was also able to streamline deinit/init to only install the driver once,
  rather than install-with-defaults/uninstall/reinstall.

Alternative would be to add a finaliser, but this is more consistent
with how most other UART objects are implemented.

8d5a8892d2 esp32: Add IDF Component Lockfiles to git repo.
This is recommended by Espressif, and it's the only way to ensure
everyone builds the same set of component versions.

The awkward part is that updating the ESP-IDF version will churn a line
in each of these files (and possibly other changes).

Adds a build-time check for lock file changes, which is either a warning or
a hard error depending on the value of MICROPY_MAINTAINER_BUILD
flag (introduced in previous commit).

This commit fixes the build issues in the MIMXRT port that arise when
explicitly disabling USB CDC support.

The console code assumed CDC support is always enabled even if it was
disabled in mpconfigport.h.  These changes make accessing CDC
conditional to that support configuration being enabled.

1f7952e749 rp2/mphalport: Fix building with USB CDC disabled.
This commit fixes the linking issues in the RP2 port that arise when
explicitly disabling USB CDC support.

The console input ringbuffer needs to be made available if dupterm
support is enabled, and the console character input function would
always attempt to read from the input ringbuffer even if CDC support is
disabled and the console isn't bound to any UART.

A fast host (eg Mac M4) may request the status for the SET_ADDRESS before
TinyUSB gets to process it.  This is because TinyUSB does not handle events
inside the USB ISR, rather it waits for the top-level thread to process
them.  Fix that by setting the USB device address as soon as
TUSB_REQ_SET_ADDRESS comes in.

This patch follows the corresponding upstream fix:

to `defined(STM32L4) || defined(STM32WB) ` in relevant files.

Also remove the dummy definition of I2C2_BASE for STM32L432xx.  It's now
provided by the dummy definition in `i2cslave.h`.

1813216 (206KB smaller).

Also has benefit of reducing D/IRAM size, increasing free memory at
runtime (167187 to 148584, -18603 bytes).

Most of this savings comes from building with -Os instead of -O2,
but about 10KB comes from using the SPI flash functions from the ROM.

bf185c37ed tests/run-natmodtests.py: Change -p/-d arguments to -t.
Following the similar change to `run-tests.py` and `run-multitests.py`.
What was previously, eg, `-p -d /dev/ttyACM0` is now `-t a0`.

6c1d1f3ad4 qemu/mcu/arm/mps2.ld: Add .ARM.exidx section to the linkerscript.
This commit fixes a linking issue on certain Arm toolchains where
library code is compiled with exception support.

If a library with exception support is included in the MicroPython
build, the linker had no place to put the stack unwinding tables
necessary to perform exception handling at runtime.  This change adds a
new section to the linkerscript (and therefore the final ELF file) where
that data can be placed into.

64cac4690f qemu/mcu/arm/errorhandler: Add ARMv7-M debug registers.
This commit extends the QEMU port's CPU error handler for the Arm target
by printing out in detail the ARMv7-M debug registers if the firmware is
compiled for such a target.

19be404ad8 qemu/arm: Add definition for the MPS2_AN500 machine.
This commit introduces a new target for the QEMU port called
"MPS2_AN500", an ARMv7-M machine with a Cortex-M7 CPU and
single-/double-precision floating point unit.

87099b5731 qemu/Makefile: Allow overriding floating point mode by boards.
This commit lets board use a different floating point mode rather than
the usual soft-float that was the original default for all QEMU-based
boards.

The configuration options are the same available in the "stm32" port.
Boards can set "MICROPY_FLOAT_IMPL" to either "float", "double", or
"none" to indicate which floating point mode they want, and optionally
"SUPPORTS_HARDWARE_FP_SINGLE" or "SUPPORTS_HARDWARE_FP_DOUBLE" can be
set to 1 to further indicate the hardware capabilities of the hardware
floating point unit, if present.
