00d6a79b3d stm32/machine_timer: Improve usability of Timer constructor and init.
Improvements are:
- Default period is 1000ms with callback disabled.
- if period is not specified then it's not updated (previously, if period
  was not specified then it was set to -1 and running the timer callback as
  fast as possible, making the REPL unresponsive).
- Use uint64_t to compute delta_ms, and raise a ValueError if the period is
  too large.
- If callback is not specified then it's not updated.
- Specifying None for the callback will disable the timer.

f842a40df4 rp2/rp2_pio: Add fifo_join support for PIO.
The PIO state machines on the RP2040 have 4 word deep TX and RX FIFOs.  If
you only need one direction, you can "merge" them into either a single 8
word deep TX or RX FIFO.

We simply add constants to the PIO object, and set the appropriate bits in
`shiftctrl`.

Resolves #6854.

e5d2ddde25 esp32/machine_pin: Use rtc_gpio_deinit instead of gpio_reset_pin.
Commit 8a917ad252 added the gpio_reset_pin()
call to make sure that pins that were used as ADC inputs could subsequently
be used as digital IO.  But calling gpio_reset_pin() will enable the
pull-up on the pin and so pull it high for a brief period.  Instead use
rtc_gpio_deinit() which will just reconfigure the pin as a digital IO and
do nothing else.

Fixes issue #7079 (see also #5771).

2668337f36 stm32/rfcore: Intercept addr-resolution HCI cmd to work around BLE bug.
The STM32WB has a problem when address resolution is enabled: under certain
conditions the MCU can get into a state where it draws an additional 10mA
or so and eventually ends up with a broken BLE RX path in the silicon.  A
simple way to reproduce this is to enable address resolution (which is the
default for NimBLE) and start the device advertising.  If there is enough
BLE activity in the vicinity then the device will at some point enter the
bad state and, if left long enough, will have permanent BLE RX damage.

STMicroelectronics are aware of this issue.  The only known workaround at
this stage is to not enable address resolution, which is implemented by
this commit.

Work done in collaboration with Jim Mussared aka @jimmo.

dd62c52a36 stm32/rfcore: Fix race condition with C2 accessing free buffer list.
Prior to this commit, if C2 was busy (eg lots of BLE activity) then it may
not have had time to respond to the notification on the IPCC_CH_MM channel
by the time additional memory was available to put on that buffer.  In such
a case C1 would modify the free buffer list while C2 was potentially
accessing it, and this would eventually lead to lost memory buffers (or a
corrupt linked list).  If all buffers become lost then ACL packets
(asynchronous events) can no longer be delivered from C2 to C1.

This commit fixes this issue by waiting for C2 to indicate that it has
finished using the free buffer list.

7ca686684e rp2: Add support for building different board configurations.
This change allows to build firmware for different rp2-based boards,
following how it is done in other ports like stm32 and esp32.  So far only
the original Pico and Adafruit Feather RP2040 are added.  Board names
should match (sans case) those in pico-sdk/src/boards/include/boards/.

Usage: Pico firmware can be build either using make as previously (it is
the default board) or by `make BOARD=PICO`.  Feather is built by `make
BOARD=ADAFRUIT_FEATHER_RP2040`.  Only the board name and flash drive size
is set, pin definition is taken from the appropriate pico-sdk board
definition.  Firmware is saved in the directory build-BOARD_NAME.

1be74b94b6 rp2/machine_uart: Add buffered transfer of data with rxbuf/txbuf kwargs.
Instantiation and init now support the rxbuf and txbuf keywords for setting
the buffer size.  The default size is 256 bytes.  The minimum and maximum
sizes are 32 and 32766 respectively.

uart.write() still includes checks for timeout, even if it is very unlikely
to happen due to a) lack of flow control support and b) the minimal timeout
values being longer than the time it needs to send a byte.

22554cf8e2 rp2/rp2_pio: Add StateMachine restart,rx_fifo,tx_fifo helper functions.
StateMachine.restart: Restarts the state machine
StateMachine.rx_fifo: Return the number of RX FIFO items, 0 if empty
StateMachine.tx_fifo: Return the number of TX FIFO items, 0 if empty

restart() seems to be the most useful one, as it resets the state machine
to the initial state without the need to re-initialise/re-create.  It also
makes PIO code easier, because then stalling as an error state can be
unlocked.

rx_fifo() is also useful, for MP code to check for data and timeout if no
data arrived.  Complex logic is easier handled in Python code than in PIO
code.

tx_fifo() can be useful to check states where data is not processed, and is
mostly for symmetry.

6f06dcaee5 rp2/moduos: Implement uos.urandom().
The implementation samples rosc.randombits at a frequency lower than the
oscillator frequency.  This gives better random values.  In addition, for
an 8-bit value 8 samples are taken and fed through a 8-bit CRC,
distributing the sampling over the byte.  The resulting sampling rate is
about 120k/sec.

The RNG does not include testing of error conditions, like the ROSC being
in sync with the sampling or completely failing.  Making the interim value
static causes it to perform a little bit better in short sync or drop-out
situations.

The output of uos.urandom() performs well with the NIST800-22 test suite.
In my trial it passed all tests of the sts 2.1.2 test suite.  I also ran a
test of the random data with the Common Criteria test suite AIS 31, and it
passed all tests too.

a66286f3a0 unix: Improve command line argument processing.
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.

4f53f462ca rp2: Import uarray instead of array in rp2 module.
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`.

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.

state.reset_mode is updated by `MICROPY_BOARD_BEFORE_SOFT_RESET_LOOP` but

boards that do not have a bootloader.  This bug was introduced by

  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.

9d674cf7ab stm32/uart: Add support for LPUART1 on L0, L4, H7 and WB MCUs.
Add LPUART1 as a standard UART.  No low power features are supported, yet.
LPUART1 is enabled as the next available UART after the standard U(S)ARTs:

    STM32WB:      LPUART1 = UART(2)
    STM32L0:      LPUART1 = UART(6)
    STM32L4:      LPUART1 = UART(6)
    STM32H7:      LPUART1 = UART(9)

On all ports: LPUART1 = machine.UART('LP1')

LPUART1 is enabled by defining MICROPY_HW_LPUART1_TX and
MICROPY_HW_LPUART1_RX in mpconfigboard.h.

d28dbcd6c7 esp32: Make machine.soft_reset() work in main.py and reset_cause().
This commit fixes two issues on the esp32:
- it enables machine.soft_reset() to be called in main.py;
- it enables machine.reset_cause() to correctly identify a soft reset.

The former is useful in that it enables soft resets in applications that
are started at boot time.  The support is patterned after the stm32 port.

c10d431819 esp32: Add basic support for Non-Volatile-Storage in esp32 module.
This commit implements basic NVS support for the esp32.  It follows the
pattern of the esp32.Partition class and exposes an NVS object per NVS
namespace.  The initial support provided is only for signed 32-bit integers
and binary blobs.  It's easy (albeit a bit tedious) to add support for
more types.

f573e73bae zephyr: Build MicroPython as a cmake target.
Refactors the zephyr build infrastructure to build MicroPython as a
cmake target, using the recently introduced core cmake rules.

This change makes it possible to build the zephyr port like most other
zephyr applications using west or cmake directly. It simplifies building
with extra cmake arguments, such as specifying an alternate conf file or
adding an Arduino shield. It also enables building the zephyr port
anywhere in the host file system, which will allow regressing across
multiple boards with the zephyr twister script.
