Some serial ports do not support specific baudrates or we are maybe not
interested in testing certain baudrate when running the fuzzing test.
Allow the user to pass multiple baudrates as a cli argument and have the
script randomly pick one of the baudrates while fuzz testing.

Tiger v1.1 has the UPDI lanes cut by default unless
ATtiny_GATE_CONTROL_d (GPIO0_C4) is pulled high.
Let's toggle that GPIO before flashing so that the UPDI can go through
to the ATtiny.
Since that GPIO was used for UART0 in Tiger v1.0, it is not supported
anymore (but those were engineering samples anyway).

Using "serial.rs485" api, the "_set_rs485_mode" callback of serialposix
is not triggered when "rs485_mode" property is updated since its setter
is overridden, making the "serial.rs485" a self-standing emulation for rs485.
Since we already have a kernel emulation for half duplex rs485, we should
make use of it by calling the respective ioctls to enable/disable it when
required.
Explicitly call "_set_rs485_mode" by passing "serial.rs485.RS485Settings"
(enable) or None (disable) instead of setting this property.

The test size can be randomized if the fuzz option is used and min/max
size are passed as cli arguments. The value holding the final test size
is a local variable ("size").
Pass it as argument to the transfer function instead of the cli argument.

package
The unofficial pure-Python gpiod package was replaced by
C-bindings-based official gpiod Python package on Pypi and the former is
deprecated.
c.f. https://pypi.org/project/gpiod/
"""
Versions 1.5.4 and prior are the deprecated, unofficial, pure-Python
bindings.
"""
While this isn't necessarily something we should worry about in the
short term, it turns out that distros actually do not package the
pure-Python, so this makes it less easy to install the dependencies for
i2c_flash.py. We could support v1.6.3 gpiod to be able to install it
from Debian package feed, however v1.6.x is in maintenance-only state
and v2.x is actively being developed with additional features, so let's
just play it safe and migrate to v2.x version.
We bump the requirements to the latest available version so that it uses
the C-bindings-based official implementation hosted on Pypi.
See https://github.com/hhk7734/python3-gpiod/issues/39 for the
discussions and history behind gpiod on Pypi.

Instead of doing Makefile magic we could use a modern build system like
meson. This commits tries to replicate the features of the current
Makefile.
To build:
# create build directory
meson build
meson compile -C build
As an alternative you can also change to the build dir and do a meson
compile.
Test reset Makefile target was implemented as a unittest
meson test -C build
As meson really does not want you to use environment variables in its
definitions you can only pass a complete environment to an external
command. To not add a wrapper script I decided to add build options.
Currently the GPIOs are set to match Ringneck.
To change the settings (for example Jaguar) use:
meson configure build -Drst_gpio_idx=13 -Drst_gpiochip_idx=2

Puma Haikou Video Demo adapter DTS actually has a model name which

After entering the flashloader mode, clearing the boot request gpio
sets the flashloader into read-only mode where the flashing tool can read
bootloader data through i2c (i2c-write ops are ignored).
This data contain:
* Bootloader version
This tool will print out all bootloader data to the console.

After entering the flashloader it is safe to set it into read-only mode
(by pulling the boot request gpio back low) until the fw_flash() routine
is actually called. This avoids having any i2c process, by mistake, write
to the wire (flash unwanted/invalid data).

This adds a pipeline for using linters. Only flake8 is used for now.
alpine/flake8 doesn't start a shell but rather execute flake8 directly.
However, GitLab CI seems to start all containers by trying to start a
shell:
```
-c if [ -x /usr/local/bin/bash ]; then
exec /usr/local/bin/bash
elif [ -x /usr/bin/bash ]; then
exec /usr/bin/bash
elif [ -x /bin/bash ]; then
exec /bin/bash
elif [ -x /usr/local/bin/sh ]; then
exec /usr/local/bin/sh
elif [ -x /usr/bin/sh ]; then
exec /usr/bin/sh
elif [ -x /bin/sh ]; then
exec /bin/sh
elif [ -x /busybox/sh ]; then
exec /busybox/sh
else
echo shell not found
exit 1
fi
```
Since flake8 is the entrypoint, it gets passed this long string which it
cannot do anything with (as opposed to the - I guess - expected `sh`).
Instead, let's replace the entrypoint of the docker image so that the
runner directly passes the script to the container.

the `updi_reset` executable's parent directory.
