The firmware for Teensy 4.0, Teensy 4.1 and MIMXRT1020_EVK are created.
Users of other MIMXRT10xx_EVK boards should be able to build the firmware
themselves, they might need specific DEBUG settings.
The Makefile had to be changed in order to build the .bin file as well.
This adds a call to mp_deinit() in the main function of the STM32 port.
This enables the use of MICROPY_PORT_DEINIT_FUNC on that port, as well as
cleaning up the GIL if threading is enabled.
Previous behaviour was: if boot.py had an exception then main.py would
still run, which is arguably unexpected behaviour.
This commit changes the behaviour so main.py is not run if boot.py has an
error.

Since the new keypad module is taking over gamepad functionality,
I'm switching to it. If this works well, I will make the change
for the remaining boards.
I noticed the build printed things like
```
Font missing 3 characters
```
.. this is why.
We can't make it an error, because Japanese has hundreds of characters
not in the font.
INCOMPATIBLE CHANGE: struct_time(1,2,3,4,5,6,7,8,9) is now _rejected_
just as on standad Python.
This incorrect constructor was added by me in #2327; I assumed
without even checking that the `struct_time` constructor was also
compatible with the `namedtuple` constructor, but it is not and has
always been rejected by standard Python (checked 2.7 and 3.9)
This commit restores the specific error message that we used for this
purpose, which was removed in the previous commit either out of laziness
or out of trying to reduce unneeded error strings. In this case, the
alternate string is too misleading (it refers to arguments, not to
sequence elements) so let's put the better message back.
As discussed in #3410, this is a micropython-compatible (though
differently named) function that allows creation of useful time
and deadline functions in pure python.
Currently when using uasyncio.start_server() the socket configuration is
done inside a uasyncio.create_task() background function. If the address
and port are already in use however this throws an OSError which cannot be
cleanly caught behind the create_task().
This commit moves the getaddrinfo and socket binding to the start_server()
function, and only creates the task if that succeeds. This means that any
OSError from the initial socket configuration is propagated directly up the
call stack, compatible with CPython behaviour.
See #7444.

This avoids the irritation of the PJRC HalfKay loader on Teensy 4.0. Block
0 and 1 are properly erased and the additional formatting in the make
script is not required anymore.
This class supports SPI bus controller mode, with blocking transfers.
SPI device numbers start at 0, to comply with the pinout of the Teensy
boards. With the configured clock frequency the fastest baud rate is
33MHz. For messages longer 16 bytes DMA is used. The class uses the
existing framework with extmod/machine_spi.c.
Extended driver options:
- drive=n with n being between 1 and 6 or PIN.POWER_1 to PIN.POWER_6.
Since the pins used by the SPI are fixed, no Pin settings can be made.
Thus the drive option is added allowing to control ringing and crosstalk
on the connection.
- gap_ns=nnnnn is the time between sent data items in a frame given in ns.
Default is 2 clock cycles.
