ASM_NOT_REG is optional, it can be synthesised by xor(reg, -1).
ASM_NEG_REG can also be synthesised with a subtraction, but most
architectures have a dedicated instruction for it.

The argument to MP_BC_MAKE_FUNCTION (raw code index) was being encoded as a
byte instead of a variable unsigned int. That meant that if there were
more than 128 merged mpy files the encoding would be invalid.
Fix that by using `mp_encode_uint(idx)` to encode the raw code index. And
also use `Opcode` constants for the opcode values to make it easier to
understand the code.

Add `pop()`, `appendleft()`, and `extend()` methods, support iteration
and indexing, and initializing from an existing sequence.
Iteration and indexing (subscription) have independent configuration flags
to enable them. They are enabled by default at the same level that
collections.deque is enabled (the extra features level).
Also add tests for checking new behavior.

This provides a MicroPython-specific berkeley-db configuration in

This updates the berkeley-db-1.xx submodule URL to a repository hosted
under the micropython organisation, and makes the following changes:
- Moves the berkeley-db header files to a single directory within the
submodule, and references all these headers with a much fuller path,
which prevents symbol clashes (eg with esp32 and queue.h).
- Removes unused/non-working files from berkeley-db, which removes all
symlinks in that repo (symlinks don't play well under Windows).
- Allows injecting an external configuration header into berkeley-db, so
the configuration doesn't have to be provided by -Dxx=yy flags to the
compiler (and possibly clashing with other symbols).
- Removes the advertising clause from the BSD 4-clause license of
berkeley-db (see relevant commit and README.Impt.License.Change for
details).

When an exception is handled and the stream is closed, but while this
happens, another exception occurs or dupterm is deactivated for another
reason, the initial deactivation crashes, because its dupterm is removed.

RemoteProc provides an API to load firmware and control remote processors.

This module implements OpenAMP's basic initialization and shared resources
support, and provides support for OpenAMP's RPMsg component, by providing
an `endpoint` type (a logical connection on top of RPMsg channel) which can
be used to communicate with the remote core.

Add a MicroPython platform for libmetal, based on the generic platform.
The MicroPython platform uses common mp_hal_xxx functions and allows ports

OpenAMP framework provides a standard inter processor communications
infrastructure for RTOS and bare metal environments. There are 3 major
components in OpenAMP: libmetal, remoteproc and RPMsg. libmetal provides
abstraction of the low-level underlying hardware, remoteproc is used for
processor Life Cycle Management (LCM) like loading firmware, starting,
stopping a core etc., and RPMsg is a bus infrastructure that enables Inter
Processor Communications (IPC) between different cores.

This new machine-module driver provides a "USBDevice" singleton object and
a shim TinyUSB "runtime" driver that delegates the descriptors and all of
the TinyUSB callbacks to Python functions. This allows writing arbitrary
USB devices in pure Python. It's also possible to have a base built-in
USB device implemented in C (eg CDC, or CDC+MSC) and a Python USB device
added on top of that.
This work was funded through GitHub Sponsors.

Note the configuration with USB disabled hasn't been tested and probably
won't build or run without further work.

If the `timeout_char` parameter is not given, we should still configure the
UART to ensure the UART is always initialized consistently. So the default
of 0 gets applied correctly, or if, for example, the baudrate was changed
the char timeout isn't still based on the old baudrate causing weird
behaviour, etc.

Prior to this commit, the pin defined for power would be used by the
esp_idf driver to reset the PHY. That worked, but sometimes the MDIO
configuration started before the power was fully settled, leading to an
error.
With the change in this commit, the power for the PHY is independently
enabled in network_lan.c with a 100ms delay to allow the power to settle.
A separate define for a reset pin is provided, even if the PHY reset
pin is rarely connected.
Fixes issue #14013.

On these targets it's possible to enter the bootloader by setting a bit in
an RTC register before resetting.
Structure it in a way that a board can still provide a custom bootloader
handler. The handler here will be the default if none is provided, for any
board based on the supported targets.

Currently only the Arduino Nano ESP32 defines a machine.bootloader handler
for ESP32. All other boards will intentionally hang.
There is no error message, nor is a NotImplementedError raised. There's no
indication if Micropython has crashed, or if the bootloader was entered but
USB is not working, which is a real problem the ESP32 bootloader has. It's
not possible escape from this hang with ^C or any other means besides
physical access to the reset pin or the ability to cycle power.
Change this to only define an implementation of machine.bootloader() when
there is a handler for it.

The new IDF v5.2 deprecated the task cleanup callback we use, so support
for the new option has been implemented in the previous commit. This also
requires a change in the sdkconfig, via a new variable
${SDKCONFIG_IDF_VERSION_SPECIFIC} which is used in all mpconfigboard.cmake
files to include an extra sdkconfig file based on the IDF version in use.
