Reasons for removal:
- It did not work properly because it stopped the hardware watchdog
timer while keeping the software watchdog running (issue #8597).
- There isn't a deinit method for the WDT in any other port.
- "The watchdog is not intended to be stopped. That is a feature."
(See #8600.)
Replace the timer-based sleep with the standard win32 call since the former
has no benefits: even though it allows specifying the time in 100uSec
chunks, the actual resolution is still limited by the OS and is never
better than 1mSec.
For clarity move all of this next to the mp_hal_delay_ms definition so all
related functions are in one place.
This replaces occurences of
foo_t *foo = m_new_obj(foo_t);
foo->base.type = &foo_type;
with
foo_t *foo = mp_obj_malloc(foo_t, &foo_type);
Excludes any places where base is a sub-field or when new0/memset is used.

This contains a string useful for identifying the underlying machine. This
string is kept consistent with the second part of the REPL banner via the
new config option MICROPY_BANNER_MACHINE.
This makes os.uname() more or less redundant, as all the information in
os.uname() is now available in the sys module.

This commit adds the git hash and build date to sys.version. This is
allowed according to CPython docs, and is what PyPy does. The docs state:
A string containing the version number of the Python interpreter plus
additional information on the build number and compiler used.
Eg on CPython:
Python 3.10.4 (main, Mar 23 2022, 23:05:40) [GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.version
'3.10.4 (main, Mar 23 2022, 23:05:40) [GCC 11.2.0]'
and PyPy:
Python 2.7.12 (5.6.0+dfsg-4, Nov 20 2016, 10:43:30)
[PyPy 5.6.0 with GCC 6.2.0 20161109] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>> import sys
>>>> sys.version
'2.7.12 (5.6.0+dfsg-4, Nov 20 2016, 10:43:30)\n[PyPy 5.6.0 with GCC ...
With this commit on MicroPython we now have:
MicroPython v1.18-371-g9d08eb024 on 2022-04-28; linux [GCC 11.2.0] v...
Use Ctrl-D to exit, Ctrl-E for paste mode
>>> import sys
>>> sys.version
'3.4.0; MicroPython v1.18-371-g9d08eb024 on 2022-04-28'
Note that the start of the banner is the same as the end of sys.version.
This helps to keep code size under control because the string can be reused
by the compiler.

To avoid any I/O glitches in mp_hal_pin_config, make sure a valid alternate
function is set in AFR first before switching the pin mode. When switching
from AF to INPUT or OUTPUT, the AF in AFR will remain valid up until the
pin mode is switched.
On ESP32 S2/S3 variants, GPIO0 through GPIO21 are valid RTC pins. This
commit defines the valid RTC_VALID_EXT_PINS for the S2/S3 variants,
otherwise, it keeps functionality the same.
For ESP32-S3 configurations, CONFIG_SPIRAM_MODE_OCT requires pins 33-37 for
PSRAM. So exclude them from the machine_pin_type and machine_pin_irq_type
object tables.
These boards do not build with IDF v4.4 because the section .iram0.text
does not fit in region iram0_0_seg. Enabling SPIRAM increases the code
size so use -Os instead of -O2 to build these boards.
Fixes issue #8260.
Some S2/S3 modules don't use the native USB interface but instead have an
external USB-UART. To make the GENERIC_S3/S3 firmware work on these boards
the UART REPL is enabled in addition to the native USB CDC REPL.
Fixes issues #8418 and #8524.

Duplication of characters is caused by re-entrant calls from separate cores
of uart_fill_tx_fifo(). This patch uses a mutex to ensure that a
re-entrant execution of the function returns without affecting the UART
FIFO.
Fixes issues #8344 and #8360.
- Add board-level configuration option to set the SMPS supply mode.
- Wait for valid voltage levels after configuring the SMPS mode.
- Wait for external supply ready flag if SMPS supplies external circuitry.
All user interface (LED, button) code has been moved to ui.c, and the
interface to this code with the rest of the system now goes through calls
to mboot_state_change(). This state-change function can be overridden by a
board to fully customise the user interface behaviour.

This follows the CPython change: https://bugs.python.org/issue21455
Socket listen backlog defaults to 2 if not given, based on most bare metal
targets not having many resources for a large backlog. On UNIX it defaults
to SOMAXCONN or 128, whichever is less.
Changes in this commit:
- Fix USB CDC RX handling to not block when unprocessed. The fix follows
5873390226.
- Fix dupterm rx.
- Remove some obsolete lines.
This commit changes the method of waiting for SPI being not busy. Instead
of the FIFO size, the TransferBusyFlag is probed.
Also, raise an error if the transfer failed.
Changes in this commit:
- Start the RTC Timer at system boot. Otherwise time.time() will advance
only if an RTC() object was created.
- Set the time to a more recent date than Jan 1, 1970, if not set. That is
2013/10/14, 19:53:11, MicroPython's first commit.
- Compensate an underflow in in timeutils_seconds_since_2000(), called by
time.time(), if the time is set to a pre-2000 date.
This is enabled at MICROPY_CONFIG_ROM_LEVEL_EXTRA_FEATURES, which is the
default for stm32. Not setting the value in mpconfigboard.h allows boards
to optionally configure it.

Prior to this commit, the USB CDC OUT endpoint got NACK'd if a character
was received but not consumed by the application, e.g. via
sys.stdin.read(). This meant that USB CDC was blocked and no additional
characters could be sent from the host. In particular a ctrl-C could not
interrupt the application if another character was pending.
To fix the issue, the approach in this commit uses a callback tud_cdc_rx_cb
which is called by the TinyUSB stack on reception of new CDC data. By
consuming the data immediately, the endpoint does not stall anymore. The
previous handler tud_cdc_rx_wanted_cb was made obsolete and removed.
In addition some cleanup was done along the way: by adding interrupt_char.c
and removing the existing code mp_hal_set_interrupt_char(). Also, there is
now only one (stdin) ringbuffer.
Fixes issue #7996.
The CAN.initfilterbanks() class method is removed, and its functionality is
replaced with the "num_filter_banks" keyword argument to the CAN
constructor and CAN.init(). This configures the filter bank split.
This new approach provides more flexibility configuring the resources used
by a given CAN instance, allowing other MCUs like H7 to fit the API. It
also brings CAN closer to how other machine peripherals are configured,
where everything is done in the constructor/init method.
This is a breaking change to the CAN API.
CAN.recv() now returns a 5-tuple, with the new element in the second
position being a boolean, True if the ID is extended.
This is a breaking change of the API for CAN.recv().
A CAN bus can have mixed classic/FD nodes. Prior to this patch the CAN API
could be configured for either standard or extended ID, but not both/mixed
operation.
This patch allows extended IDs to be filtered and enabled on a per-message
basis, in send(), setfilter() and clearfilter().
This is a breaking change to the API: init() no longer accepts the extframe
keyword argument.
- Enable CAN FD frame support and BRS.
- Optimize the message RAM usage per FDCAN instance.
- Document the usage and different sections of the Message RAM.
This commit adds support for machine.I2S on the mimxrt port. The I2S API
is consistent with the existing stm32, esp32, and rp2 implementations.
I2S features:
- controller transmit and controller receive
- 16-bit and 32-bit sample sizes
- mono and stereo formats
- sampling frequencies from 8kHz to 48kHz
- 3 modes of operation:
- blocking
- non-blocking with callback
- uasyncio
- configurable internal buffer
- optional MCK
