STM32L476RG MCU of NUCLEO_L476RG board has 6 UART/USART units in total
(USART1, USART2, USART3, UART4, UART5 and LPUART1), but only UART2,
connected to REPL, was defined and available in Python code.
Defined are all 5 remaining UART/USART units including LPUART1.

This commit simplifies the customisation of the main MicroPython execution
loop (4 macros are reduced to 2), and allows a board to have full control
over the execution (or not) of boot.py and main.py.
For boards that use the default start-up code, there is no functional
change in this commit.

Per CPython everything which comes after the command, module or file
argument is not an option for the interpreter itself. Hence the processing
of options should stop when encountering those, and the remainder be passed
as sys.argv. Note the latter was already the case for a module or file but
not for a command.
This fixes issues like 'micropython myfile.py -h' showing the help and
exiting instead of passing '-h' as sys.argv[1], likewise for
'-X <something>' being treated as a special option no matter where it
occurs on the command line.
Some forum users noticed that `sm.exec()` took longer the more was present
on the flash filesystem connected to the RP2040. They traced this back to
the `array` import inside `asm_pio()`, which is causing MicroPython to scan
the filesystem.
uarray is a built-in module, so importing it shouldn't require scanning the
filesystem.
We avoid moving the import to the top-level in order to keep the namespace
clean; we don't want to accidentally expose `rp2.array`.
Support for C++ was added in 97960dc7de but
that commit didn't include the C++ exception handling table in the binary
firmware image. This commit fixes that.

This is a workaround for errata RP2040-E5, and is needed to make USB more
reliable on certain USB ports.

It's a bit of a pitfall with user C modules that including them in the
build does not automatically enable them. This commit changes the docs and
examples for user C modules to encourage writers of user C modules to
enable them unconditionally. This makes things simpler and covers most use
cases.
See discussion in issue #6960, and also #7086.

It was noticed that the esp32 port didn't build ulab correctly. The
problem was a multiple defintion of the 'mp_hal_stdout_tx_str' and
'mp_hal_stdout_tx_strn_cooked' functions.
They were defined in stdout_helpers.c but also in the
ports/esp32/mphalport.c.
Fixed by removing stdout_helpers.c from the build.

Support for User C and C++ modules was lost due to upgrading the esp32 to
the latest CMake based IDF from the GNUMakefile build process.
Restore the support for the esp32 port by integrating with the approach
recently added for the rp2 port.

This USB feature is currently not supported. With this flag enabled (and
the feature not implemented) the USB serial will stop working if there is a
delay of more than about 2 seconds between messages, which can occur with
USB autosuspend enabled.
Fixes issue #6866.
The parts that are generic are added to py/ so they can be used by other
ports that use CMake.
py/usermod.cmake:
* Creates a usermod target to hang user C/CXX modules from.
* Gathers sources from user C/CXX modules and libs for QSTR scan.
ports/rp2/CMakeLists.txt:
* Includes py/usermod.cmake.
* Links the resulting usermod library to the MicroPython target.
py/mkrules.cmake:
Add cxxflags to qstr.i.last custom command for CXX modules:
* MICROPY_CPP_FLAGS so CXX modules will find includes.
* -DNO_QSTR to fix fatal error missing "genhdr/qstrdefs.generated.h".
Usage:
The rp2 port can be linked against user C modules by running:
make USER_C_MODULES=/path/to/module/micropython.cmake
CMake will print a list of included modules.

This commit simplifies and cleans up the bare-arm port, and adds just
enough system and library code to make it execute on an STM32F405 MCU.
The mpconfigport.h configuration is simplified to just specify those
configuration values that are different from the defaults. And the
addition of -fdata-sections and -ffunction-sections means the final
firmware is smaller than it previously was, by about 4200 bytes.
A README is also added.

The GNU Make dir command uses spaces as item separator so it does not
work for e.g building the STM32 port on Cygwin with a default Arm
installation in "c:/program files (x86)/GNU Arm Embedded Toolchain".
Fix by using POSIX dirname on a quoted path instead.
When UART is used for REPL and the MCU frequency is changed, the UART
has to be re-initialised. Besides that the UART may have to be recreated
after a frequency change, but with USB REPL this is not a problem.
Thanks to @HermannSW for spotting and providing the change.
Using the standard machine.freq().
The safe ranges tested were 10 and 12-270MHz, at which USB REPL still
worked. Requested settings can be checked with the script:
pico-sdk/src/rp2_common/hardware_clocks/scripts/vcocalc.py. At frequencies
like 300MHz the script still signaled OK, but USB did not work any more.
sm.get(buf) was waiting for one item more than the length of the supplied
buffer. Even if this item was not stored, sm_get would block trying to get
an item from the RX fifo.
As part of the fix, the edge case for a zero length buffer was moved up to
the section where the function arguments are handled. In case of a zero
length buffer, sm.get() now returns immediately that buffer.
The bitmasks supplied for initialization of out/set/sideset were only 8 bit
instead of 32. This resulted in an error, that not more than 8 consecutive
pins would get initialized.
Fixes issue #6933.
This allows the user to enable wake-up sources using the EWUP bits, on F7
MCUs.
Disabling the wake-up sources while clearing the wake-up flags follows the
reference manual and ST examples.
state.reset_mode is updated by `MICROPY_BOARD_BEFORE_SOFT_RESET_LOOP` but
not passed to `init_flash_fs`, and so factory reset is not executed on
boards that do not have a bootloader. This bug was introduced by
4c3976bbcaFixes#6903.
A corrupt filesystem may lead to a request for a block which is out of
range of the block device limits. Return an error instead of passing the
request down to the lower layer.
Two of the defaults have also changed in this commit:
- MICROPY_HW_RFCORE_BLE_LSE_SOURCE changed from 1 to 0, which configures
the LsSource to be LSE (needed due to errata 2.2.1).
- MICROPY_HW_RFCORE_BLE_VITERBI_MODE changed from 0 to 1, which enables
Viterbi mode, following all the ST examples.
