It was set to 133Mhz, but that is not stable. Reduce to 100MHz.
The UF2 bootloader runs at 100MHz, so no need for a change of the
bootloader.

This works similarly to the existing support in "bare metal" make ports,
with the caveat that CMake will only set this value on a clean build and
will reuse the previous value otherwise.
This is slightly different to the CMake built-in support for CFLAGS,
as this variable is used when evaluating source files for qstr
generation, etc.

Regression in 3af006ef meant that pendsv.c no longer compiled if threads
were disabled in the build config. Add an implementation based on the
earlier one (simple counter) for the non-threads case.
It seems like with the current usage patterns there's no need for the
counter to be incremented/decremented atomically on a single core config.

This adds a multi-test for DTLS server and client behaviour. It works on
all ports that enable this feature (eg unix, esp32, rp2, stm32), but
bare-metal ports that use lwIP are not reliable as the DTLS server because
the lwIP bindings only support queuing one UDP packet at a time (that needs
to be fixed).
Also, to properly implement a DTLS server sockets need to support
`socket.recvfrom(n, MSG_PEEK)`. That can be implemented in the future.

This commit enables support for DTLS, i.e. TLS over datagram transport
protocols like UDP. While support for DTLS is absent in CPython, it is
worth supporting it in MicroPython because it is the basis of the
ubiquitous CoAP protocol, used in many IoT projects.
To select DTLS, a new set of "protocols" are added to SSLContext:
- ssl.PROTOCOL_DTLS_CLIENT
- ssl.PROTOCOL_DTLS_SERVER
If one of these is set, the library assumes that the underlying socket is a
datagram-like socket (i.e. UDP or similar).
Our own timer callbacks are implemented because the out of the box
implementation relies on `gettimeofday()`.
This new DTLS feature is enabled on all ports that use mbedTLS.
This commit is an update to a previous PR #10062.
Addresses issue #5270 which requested DTLS support.

Despite the code comments claiming one is sufficient, the mDNS application
is capable of using up to twelve timers. Three per IP protocol are started
at once in `mdns_start_multicast_timeouts_ipvX`, then another two per
protocol can be started in `mdns_handle_question`. Further timers can be
started for two additional callbacks.
Having certain timers, such as `MDNS_MULTICAST_TIMEOUT`, fail to start due
to none being free will break mDNS forever as the app will never realize
it's safe to transmit a packet. Therefore, this commit goes somewhat
overkill and allocates the maximal amount of timers; it's uncertain if all
can run simultaneously, or how many callback timers are needed.
Each timer struct is 16 bytes on standard 32 bit builds. Plus, say, 8
bytes of allocater overhead, that's 288 more bytes of RAM used which
shouldn't be too horrible. Users who don't need mDNS can manually disable
it to recover the RAM if necessary.
This fixes mDNS on W5500_EVB_PICO (among other boards). Before, mDNS would
work for a bit after connection until the host's cache expired a minute or
two later. Then the board would never respond to further queries. With
this patch, all works well.

The linker scripts for most of these microcontrollers contain a
non-contiguous flash section for the ID code that results in big binary
files, which exceed the flash size. This commit removes the ID code
section from the main firmware binary, and outputs it to a separate binary,
which can be deployed manually if ID code is enabled.

The current code evaluates `pyb.RTC().datetime()` resulting in a remote
side exception, as `pyb` is not defined on most ports (only stm32).
The code should evaluate `machine.RTC().datetime()` and hence return the

It's not necessary to support this, which allows an arbitrary memory
address to be specified and potentially allows invalid memory accesses.
Requiring an object with the buffer protocol is safer, and also means that
the length of the region is always specified.

This commit implements a small subset of the CPython `marshal` module. It
implements `marshal.dumps()` and `marshal.loads()`, but only supports
(un)marshalling code objects at this stage. The semantics match CPython,
except that the actual marshalled bytes is not compatible with CPython's
marshalled bytes.
The module is enabled at the everything level (only on the unix coverage
build at this stage).

The `mp_obj_code_t` and `mp_type_code` code object was defined internally
in both `py/builtinevex.c` and `py/profile.c`, with completely different
implementations (the former very minimal, the latter quite complete).
This commit factors these implementations into a new, separate source file,
and allows the code object to have four different modes, selected at
compile-time:
- MICROPY_PY_BUILTINS_CODE_NONE: code object not included in the build.
- MICROPY_PY_BUILTINS_CODE_MINIMUM: very simple code object that just holds
a reference to the function that it represents. This level is used when
MICROPY_PY_BUILTINS_COMPILE is enabled.
- MICROPY_PY_BUILTINS_CODE_BASIC: simple code object that holds a reference
to the proto-function and its constants.
- MICROPY_PY_BUILTINS_CODE_FULL: almost complete implementation of the code
object. This level is used when MICROPY_PY_SYS_SETTRACE is enabled.

This commit adds a clarification for the ESPNow module's documentation
regarding its "config" method.
The original documentation for that method could be interpreted as having
all its configuration keys being able to be queried, but the "rate"
configuration key is actually write-only due to ESP-IDF's lack of a way to
retrieve that bit of information from the radio's configuration. The
documentation changes highlight the fact that said configuration key is
actually write-only.

The `rp2` package use a global dict `_pio_funcs` to populate a namespace
for `@asm_pio` functions to be executed in. That dict is not cleaned up
after use, keeping references to bound methods of a `PIOASMEmit`. By not
setting/clearing all the functions, `asm_pio_encode` unintentionally allows
the use of the old directives (harmless) as well as `jmp` (in general,
produces the wrong output).
Fix that by making sure `_pio_funcs` is returned to its original state
after using it:
- For `@asm_pio` update the target dict from `_pio_funcs` and then set
additional functions as needed, leaving `_pio_funcs` unchanged.
- For `asm_pio_encode`, borrow `_pio_funcs` to use as globals (avoiding a
bunch of memory alloc/free) but delete the instruction entries after use.

Add support for `mpremote mip install package.json` where `package.json` is
a json file on the local filesystem.
Without this, package json files can only be loaded from http, https,
github or gitlab URLs.
This is useful for testing `package.json` files for pacages in development
and for constructing one's own `package.json` files for Python packages
which are not yet available for installation using mip.

The flash clock frequency may have been set to a different value by a
bootloader. Set the frequency according to the configured value. Use a
table of pre-calculated dividers to get the closest value for the flash
frequency, achieving for MIMXRT10xx:
30 -> 30.85 MHz
50 -> 49.65 MHz
60 -> 60 MHz
75 -> 75.13 MHz
80 -> 80 MHz
100 -> 99.31 Mhz
133 -> 132.92 MHz
166 -> 166.15 MHz
for MIMXRT1176:
30 -> 31 MHz
50 -> 52.8 MJz
60 -> 58.7 MHz
75 -> 75.4 MHz
80 -> 75.4 MHz
100 -> 105.6 MHz
133 -> 132 MHz
166 -> 176 MHz

And use these to initialize the LUT table properly for the various flash

Allowing to use e.g. the Adafruit bootloaders with MicroPython. The .uf2
file is created in addition to the .bin and .hex files allowing to use the
latter ones without the bootloader for debugging and testing.
Changes:
- Set the location of the ISR Vector and .text segment to 0x6000C000 and
0x6000C400.
- Reserve an area at the start of ITCM for a copy of the interrupt vector
table and copy the table on reset to this place.
- Extend `machine.bootloader()` by setting the magic number to enable the
bootloader on reset.
- Create a .uf2 file which skips the segments below 0x6000C000.
The bootloader has to be installed as a preparation step using the board
specific methods, but then the firmware's .uf2 file version can be
installed using the bootloader. The bootloader can be invoked with:
- double reset
- calling machine.bootloader()
- Using the touch1200 method
Double reset is hard to achieve on MIMXRT boards, since there is no clean
reset pin. Some MIMXRT boards provide it by switching the power.
Some boards are excluded from the .uf2 build:
- MIMXRT1050_EVK: The uf2 bootloader is built for the QSPI version of the
board. MicroPython supports the Hyperflash version.
- MIMXRT1176_EVK: No support for this board yet, but it should be possible.
