These changes allow the firmware to support both the REV-1 and REV-2
versions of the board:
- Freeze the new device drivers used in REV-2.
- Add a board-level module that abstracts the IMU chipset.
Changes are:
- Freeze micropython-lib time module to get strftime.
- Reserve the last 1MB of QSPI flash for (optional) WiFi firmware storage.
- Disable SD card mount on boot.
- Enable high-speed BLE firmware download.
This is handy when you are doing builds outside of the Git repository but
still want to record that information.

This is for boards without networking support so that the default boot.py
continues to work.
Also update boot.py to use network.country and network.hostname instead.

This removes the previous WiFi driver from drivers/cyw43 (but leaves behind
the BT driver), and makes the stm32 port (i.e. PYBD and Portenta) use the
new "lib/cyw43-driver" open-source driver already in use by the rp2 port.

Rather than duplicating the implementation of `network`, this allows
ESP8266 to use the shared one in extmod. In particular this gains access
to network.hostname and network.country.
Other than adding these two methods, there is no other user-visible change.

This allows for a port (e.g. esp8266/esp32) to use extmod/modnetwork.c
and provide the globals dict, rather than just a list of interfaces.
When this is used, the default implementation of `network.route` and the
NIC list is not enabled.
Also splits out the LWIP-specific helpers from modnetwork.c into
network_lwip.c.

This provides a standard interface to setting the global networking config
for all interfaces and interface types.
For ports that already use either a static hostname (mimxrt, rp2) they will
now use the configured value. The default is configured by the port
(or optionally the board).
For interfaces that previously supported .config(hostname), this is still
supported but now implemented using the global network.hostname.
Similarly, pyb.country and rp2.country are now deprecated, but the methods
still exist (and forward to network.hostname).
Because ESP32/ESP8266 do not use extmod/modnetwork.c they are not affected
by this commit.

Without this it's possible to get a compiler error about the comparison
always being true, because MP_BINARY_OP_LESS is 0. And it seems that gcc
optimises these 6 equality comparisons into the same size machine code as
before.
Prior to this fix, pow(1.5, inf) and pow(0.5, -inf) (among other things)
would incorrectly raise a ValueError, because the result is inf with the
first argument being finite. This commit fixes this by allowing the result
to be infinite if the first or second (or both) argument is infinite.
This fix doesn't affect the other three math functions that have two
arguments:
- atan2 never returns inf, so always fails isinf(ans)
- copysign returns inf only if the first argument x is inf, so will never
reach the isinf(y) check
- fmod never returns inf, so always fails isinf(ans)

Currently, certain mpremote filesystem operations can fail on Windows due
to a mixing of '/' and '\' for path separators. Eg if filesystem_command()
is called with a destination that ends in / then dest.endswith(os.path.sep)
will return False, which gives the wrong behaviour (it does end in a path
separator).
For similar reasons to 7e9a15966a, it's best
to use '/' everywhere in pyboard.py and mpremote, because the target device
understands only '/'. mpremote already does this, so the remaining place
to fix it is in pyboard.y, to convert all incoming paths to use '/' instead
of '\'.
This effectively reverts 57fd66b80f which
tried to fix the problem in a different way.

This allows the entire configuration to be defined in a single file,
including the logic for including pyboard.py and automatically versioning
based on the git tag.
Building the package works both via `python -m build` as well as
`hatch build`. `python -m build ` has the advantage of automatically
fetching all dependencies, you don't need to manually install any hatch
packages.
In order to make the versioning work, and also keep things simpler for end
users, mpremote releases will now be the same as MicroPython releases and
use the same tag. The version strings for mpremote will look like:
- X.Y.Z -- clean build at the tag
- X.Y.Z.postN+gHASH -- clean build, N revisions from the most recent tag
- X.Y.Z.postN+gHASH.dYYYYMMDD -- dirty build, N revisions from out
This commit extends on the idea from #8404.

This allows:
$ make BOARD_DIR=path/to/board
to infer BOARD=board, rather than the previous behavior that required
additionally setting BOARD explicitly.
Also makes the same change for VARIANT_DIR -> VARIANT on Unix.

This RNG passes many of the Diehard tests and also the AIS31 test suite.
The RNG is quite slow, delivering 200bytes/s.
Tested on boards with and without a crystal.
It turned out that the result of calling ticks_us() was always either odd
or even, depending on some internal state during boot. So the us-counter
was set to a 2 MHz input and the result shifted by 1. The counting period
is still long enough, since internally a (now) 63 bit value is used for us.
By using the phase jitter between the DFLL48M clock and the FDPLL96M clock.
Even if both use the same reference source, they have a different jitter.
SysTick is driven by FDPLL96M, the us counter by DFLL48M. As a random
source, the us counter is read out on every SysTick and the value is used
to accumulate a simple multiply, add and xor register. According to tests
it creates about 30 bit random bit-flips per second. That mechanism will
pass quite a few RNG tests, has a suitable frequency distribution and
serves better than just the time after boot to seed the PRNG.
Allowing to increase the clock a little bit to 54Mhz. Not much of a gain,
but useful for generating a RNG entropy source from the jitter between
DFLL48M and FDPLL96M.
Remove two SPARKFUN_SAMD51_THINGS_PLUS pin definitions. There were
definitions of TXD and RXD, but these pins do not exist on the board. They
were only shown in the schematics.
Also remove any reference to LED_. This is just a text change, no
functional change.
Since commit d6d8722558, modbtree.c is
included unconditionally in the build (if SRC_EXTMOD_C is used). So guard
the includes of system headers files in case a target doesn't have them.

Now that the code-size-check CI action gives a nice report (as a comment)
on the code size difference, it's possible to have a few more ports
reported there. In this commit, unix, stm32 and rp2 are added. Unix
represents non-MCU builds, and stm32 and rp2 represent ARM-based builds,
for ports that have lots of features enabled.

For compatibility with other ports. Code increase up to ~1250 bytes for
SAMD21. The feature is configurable via MICROPY_PY_MACHINE_PIN_BOARD_CPU
in case flash memory is tight.
