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.

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.

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
hashable. Since MicroPython has an implicit fallback when the unary_op
slot is empty, we need to fill this slot.

Since converting to variable sized slots in mp_obj_type_t, we can now
reduce the code size a bit by removing mp_generic_unary_op() and the
corresponding slots where it is used. Instead we just implement the
generic `__hash__` operation in the runtime.

When the network module was first introduced in the esp8266 port in
ee3fec3167 there was only one interface (STA)
and, to save flash, the WLAN object was aliased to the network module,
which had just static methods for WLAN operations. This was subsequently
changed in 9e8396accb when the AP interface
was introduced, and the WLAN object became a true class.
But, network.WLAN remained a function that returned either the STA or AP
object and was never upgraded to the type itself. This scheme was then
copied over to the esp32 port when it was first introduced.
This commit changes network.WLAN from a function to a reference to the WLAN
type. This makes it consistent with other ports and network objects, and
allows accessing constants of network.WLAN without creating an instance.

Previously when using --via-mpy, the file was compiled to tests/<tmp>.mpy
and then run using `micropython -m <tmp>` in the current cwd
(usually tests/). This meant that an import in the test would be resolved
relative to tests/.
This is different to regular (non-via-mpy) tests, where we run (for
example) `micropython basics/test.py` which means that an import would be
resolved relative to basics/.
Now --via-mpy matches the .py behavior. This is important because:
a) It makes it so import tests do the right thing.
b) There are directory names in tests/ that match built-in module names.
Furthermore, it always ensures the cwd (for both micropython and cpython)
is the test directory (e.g. basics/) rather than being left unset. This
also makes it clearer inside the test that e.g. file access is relative to
the Python file.
Updated tests with file paths to match.

Building the Pico-W needs the MICROPY_PY_NETWORK_CYW43 flag to be set in
order to include building the CYW43 Wifi driver. But then mp_hal_get_mac()
handles the MAC assignment for all nics the "CYW43 way", copying the real
MAC provided by the WiFi hardware. This will fail for all other NIC types,
resulting in an invalid MAC address.
The solution in this commit is to add a check for the NIC type parameter
idx and handle the MAC address respectively.
Convert to an absolute path to always reliably locate manifest.py. This is
already done in Makefile, but is also needed in CMakeLists.txt if cmake is
invoked directly.

Currently rp2.StateMachine.exec(instr_in) requires that the instr_in
parameter be a string representing the PIO assembly language instruction
to be encoded by rp2.asm_pio_encode(). This commit allows the parameter
to also be of integral type. This is useful if the exec() method is
being called often where the use of pre-encoded machine code is
desireable.
This commit still supports calls like:
sm.exec("set(0, 1)")
It also now supports calls like:
# Performed once earlier, maybe in __init__()
assembled_instr = rp2.asm_pio_encode("out(y, 8)", 0)
# Performed multiple times later as the PIO state machine is
# configured for its next run.
sm.exec(assembled_instr)
The existing examples/rp2/pio_exec.py and examples/rp2/pio_pwm.py that
exercise the rp2.StateMachine.exec() method still work with this change.

FSP v4.4.0 refers to CMSIS V5.4.1, and __COMPILER_BARRIER() is used in bsp.
On the other hand, lib/cmsis is V5.1.0 and the macro is not defined.
Therefore, compile error happens.
As the workaround, the macro definition is added.
If lib/cmsis is updated in the future, this addition can be removed.
