This one sets the flash image length properly for the teensy loader, such
that the file system is not erased. It was already set in commit
8e54225140 but got lost when the MIMXRT1176
board was added.

Three bugs have been fixed in this commit:
1. When the duty was set with duty_u16(), changing the freq with pwm.freq()
would not keep relative duty rate, but the absolute pulse duration.
2. Fix another inconsistency when displaying the PWM pin's properties of a
QTMR channel.
3. Improve the error checks for the second channel being a PWM pin and pin
pairs to be a FLEXPWM A/B pair.

These have by default FAT support. The SAMD21 build does not support FAT.
The nrf port also implements os.sync(), but has it's own copy of moduos.c.
Code size increases seen: 40 to 56 bytes.

Avoiding code duplication. To enable it, set MICROPY_PY_UOS_SYNC in the
port's mpconfigport.h. It is operational only for FAT file system. For
other filesystems it's a no-op.

The hal_entry.c code is duplicated across all boards, so consolidate it to
a common ra_hal.c file. And remove the hal_entry() function because it
simply calls main().

By specifying rts=pin(x) and/or cts=Pin(x) in the constructor. The pad
numbers for the UART pins are fix in this case: TX must be at pad 0, RX at
pad 1, RTS at pad 2 and CTS at pad 3.
repr(uart) shows the pin names for rts and cts, if set. In case of a RX
overflow, the rx interrupt will be disabled instead of just discarding the
data. That allows RTS to act.
If RTS is inactive, still 2 bytes can be buffered in the FIFO.

With Crystal: set the crystal startup wait time to 1 second. It was 2
seconds before, and that seeemed too long.
With USB-Sync: scan for up to 1 second for the USB to be registered and
carry on with boot as soon as it it. Before, the code just waited for
500ms.
Side change: improve related comments.

These include ADC, DAC, I2C, SoftI2C, SPI, SoftI2C, PWM, UART, pulse. This
is useful for devices like the Adafruit Trinket series which have almost no
accessible GPIO pins.

If sockets were open when calling soft reset, gc_sweep_all() would try to
close them. In case of e.g. the NINA WiFi handler, connected through SPI,
spi_transfer() would be called for command exchange with the NINA module.
But at that time SerCom was already disabled.
Moving sercom_deinit_all() behind gc_sweep_all() solves this issue.

Such that they are easier to adapt. The maximum code size is set by:
MICROPY_HW_CODESIZE=xxxK
in mpconfigmcu.mk for the MCU family as default or in mpconfigboard.mk for
a specific board. Setting the maximum code size allows the loader to error
out if the code gets larger than the space dedicated for it.

This commit adds the "--escape-non-printable" option to the repl command.
When specified the REPL console will escape non-printable characters,
printing them as their hex value in square brackets.
This escaping behaviour was previously the default and only behaviour, but
it is now opt-in.
As part of this change, the speed of echoing device data to the console is
improved by by reading and writing in chunks.

Change UART clock source on S3/C3 so the UART can operate when CPU
frequency is below 80MHz. This allows the UART to remain operational when

Once all the firmware has been flashed and the final signatures checked,
mboot writes the "all good" byte into the header of the application. This
step uses the buffer firmware_head which, if unaligned in the build, fails
when cast to a uint64_t* in flash.c.

Update docs/library/espnow.rst to add:
- guidance on using WLAN.config(pm=WLAN.PM_NONE) for reliable
espnow performance while also connected to a wifi access point;
- guidance on receiving encrypted messages;
- correction for default value of "encrypt" parameter (add_peer());
- guidance on use of ESPNow.irq(): recommand users readout all messages
in the buffer each time the callback is called.

This adds a unary_op implementation for the dict_view type that makes

As per https://bugs.python.org/issue408326, the slice object should not be

slot is empty, we need to fill this slot.
