Krzysztof Adamski 6409bbcb72 mimxrt: Move calc_weekday helper function to timeutils.
This function may be useful for other ports as well so lets move it to
timeutils so it can be reused.

Amir Gonnen cb332ddae8 unix/modffi: Add option to lock GC in callback, and cfun access.
Add an optional 'lock' kwarg to callback that locks GC and scheduler.  This
allows the callback to be invoked asynchronously in 'interrupt context',
for example as a signal handler.

Also add the 'cfun' member function to callback, that allows retrieving the
C callback function address.  This is needed when the callback should be
set to a struct field.

See related #7373.

David Lechner 259d9b69fe py/mpstate: Schedule KeyboardInterrupt on main thread.
This introduces a new macro to get the main thread and uses it to ensure
that asynchronous exceptions such as KeyboardInterrupt (CTRL+C) are only
scheduled on the main thread. This is more deterministic than being
scheduled on a random thread and is more in line with CPython that only
allow signal handlers to run on the main thread.

Thomas Wenrich 060066804a esp32/modnetwork: Add "reconnects" option to WLAN STA interface.
This adds a wlan.config(reconnects=N) option to set the number of reconnect
attempts that will be made if the WLAN connection goes down.  The default
is N=-1 (infinite retries, current behavior).  Setting
wlan.config(reconnects=0) will disable the reconnect attempts.

A nice side effect of reconnects=0 is that wlan.status() will report the
disconnect reason now.  See related issue #5326.

robert-hh 689476c576 mimxrt/machine_uart: Add the UART class to the machine module.
The implementation uses the LPUARTx devices.  Up to 8 UARTs can be used,
given that the pins are accessible.  E.g. 8 on Teensy 4.1, 5 on
MIMXRT1020_EVK.

For Tennsy 4.0 and 4.1 the UART numbers are as printed on the pinout 1..N.
The MIMXRT10xx-EVK boards have only one UART named, which gets the number
1.  All other UART are assigned to different Pins:

MIMXRT1010-EVK:
    D0/D1   UART 1
    D6/D7   UART 2
    A0/D4   UART 3

MIMXRT1020-EVK:

This change moves the datetime tuple format back to the one used by all the
other ports:

    (year, month, day, weekday, hour, minute, second, microsecond)

Weekday is a number between 0 and 6, with 0 assigned to Monday.  It has to
be provided when setting the RTC with datetime(), but will be ignored on
entry and calculated when needed.

The weekday() method was removed, since that is now again a part of the
datetime tuple.

The now() method was updated so it continues to return a tuple that matches
CPython's datetime module.

Krzysztof Adamski 37d01d4be3 rp2/machine_rtc: Add initial support for RTC.
Initial support for machine.RTC on rp2 port. It only supports datetime()
method and nothing else. The method gets/returns a tuple of 8 items, just
like esp32 port, for example, but the usec parameter is ignored as the RP2
RTC only works up to seconds precision.

The Pico RTC isn't very useful as the time is lost during reset and there
seems to be no way to easily power up just the RTC clock with a low current
voltage, but still there seems to be use-cases for that, see issues #6831,
and a Thonny issue #1592. It was also requested for inclusion on v1.15
roadmap on #6832.

robert-hh 2f365d234e mimxrt/machine_rtc: Add the RTC class to the machine module.
Initial version, using the LP RTC clock.  It provides setting the date and

rtc.datetime() or rtc.now().  The method weekday() reports the weekday of
the current date.  It starts with 0 for Monday.

The tuple order for datetime() and now() matches the CPython sequence:
(year, month, day, hour, minute, second, microsecond, TZ).  TZ is ignored
and reported as None.  Microsecond is provided at a best effort.

If a battery is not supplied, the default boot date/time is 1970/1/1 0:0:0.
With a battery, the clock continues to run even when the board is not
powered.  The clock is quite precise.  If not, using rtc.calibration() may
help.

This commit adds full support for a filesystem on all boards, with a block
device object mimxrt.Flash() and uos.VfsLfs2 enabled.

Main changes are:
- Refactoring of linker scripts to accomodate reserved area for VFS.  VFS
  will take up most of the available flash. 1M is reserved for code.  9K is
  reserved for flash configuration, interrupts, etc.
- Addition of _boot.py with filesystem init code, called from main.c.
- Definition of the mimxrt module with a Flash class in modmimxrt.[ch].
- Implementation of a flash driver class in mimxrt_flash.c.  All flashing
  related functions are stored in ITCM RAM.
- Addition of the uos module with filesystem functions.
- Implementation of uos.urandom() for the sake of completeness of the uos
  module.

It uses sample code from CircuitPython supplied under MIT license, which
uses the NXP SDK example code.

Done in collaboration with Philipp Ebensberger aka @alphaFred who
contributed the essential part to enable writing to flash while code is
executing, among other things.

Damien George ea81bcf1c0 stm32/mboot: Leave bootloader from thread mode, not from IRQ.
Leaving the bootloader from an IRQ (eg USB or I2C IRQ) will not work if
MBOOT_LEAVE_BOOTLOADER_VIA_RESET is disabled, ie if mboot jumps directly to
the application.  This is because the CPU will still be in IRQ state when
the application starts and IRQs of lower priority will be blocked.

Fix this by setting a flag when the bootloader should finish, and exit the
bootloader always from the main (top level) thread.

This also improves the USB behaviour of mboot: it no longer abruptly
disconnects when the manifest command is sent.

a problem if left unconnected.  But the output pins don't need a pull up
(they were originally all configured with pull up in commit
8f7491a109).

If needed, the pull-ups can be disabled in Python using machine.Pin after
the UART is constructed.

See issue #4369.

Damien George a96afae90f stm32/sdio: Fix case of SDIO DMA turning off mid transfer.
The DMA driver will turn off DMA if it hasn't been used for an amount of
time (to save power).  The SDIO driver for cyw43 WLAN was not informing the
DMA driver that it was using DMA and there was a chance that the DMA would
turn off in the middle of an SDIO DMA transfer.  The symptoms of this would
be printing of SDIO error messages and a failure to communicate with the
cyw43 WLAN module.

This commit fixes this issue by changing the SDIO driver to use the
dma_nohal_XXX API to initialise and start the DMA.

A board can now customise mboot with:

  different LEDs for mboot compared to the application
- MBOOT_BOARD_LED_INIT: if it needs a fully customised LED init function
- MBOOT_BOARD_LED_STATE: if it needs a fully customised LED state-setting
  function
- MBOOT_BOARD_GET_RESET_MODE: if it needs a fully customised function to
  get the reset mode

With full customisation, the only requirement is a single LED to show the
status of the bootloader (idle, erasing, flashing, etc), which can be
configured to do nothing if needed.

Damien George 647fa63f9c stm32/softtimer: Support static soft timer instances.
This adds support for making static (ie not on the Python GC heap) soft
timers.  This can be useful for a board to define a custom background
handler, or eventually for BLE/network processing to use instead of systick
slots; it will be more efficient using soft timer for this.

The main issue with using the existing code for static soft timers is that
it would combine heap allocated and statically allocated soft_timer_entry_t
instances in the same pairing-heap data structure.  This would prevent the
GC from tracing some of the heap allocated entries (because the GC won't
follow pointers outside the heap).

This commit makes it so that soft timer entries are explicitly marked,
instead of relying on implicit marking by having the root of the pairing
heap in the root pointer section.  Also, on soft reset only the heap-
allocated soft timers are deleted from the pairing heap, leaving the
statically allocated ones.

Damien George 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.

Damien George 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.

jahr 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.

robert-hh 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.

robert-hh 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.

robert-hh 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.
