Description
With this PR, automatic pin generation works fine. I have the following changes there:

• Python scripts that handle the automatic generation of csv and headers in build (make-pins-csv and make-pins)
• Makefile changes to integrate the sources with the rest
• The changes in machine_adcblock has to be so for now until we extend machine_pin structure to incorporate alternate functions

Good job! :)
As discussed, if the csv is not necessary, removing all those file creation, generation etc, would make our port easier and simpler to maintain.

[jaenrig-ifx]

These can go in the corresponding mpconfigport.mk or?

[NikhitaR-IFX]

Or rather more suitable in mpconfigboard.mk? Because each board will have one such variable set no?

[jaenrig-ifx]

Yes, sorry. I meant mpconfigboard.mk sorry :)

[NikhitaR-IFX]

Agreed and updated

[jaenrig-ifx]

why clean_csv after build?

[NikhitaR-IFX]

We don't need to retain the csv files as part of our sources. These are only intermediate files used by make-pins.py to generate the sources in build. But as soon as that is done, we don't need to save or maintain these csv files. I tried to clear them out right after make_pins target is invoked but that does not work because it complains to me as shown in image.

And I understand that why. qstr generation is eventually dependent on pins.csv and even before pins_qstr.h is generated csv files are removed. But I don't know how to fix that order anymore :|

[jaenrig-ifx]

We will refine a bit the makefile later. It is fine for now 👍

[NikhitaR-IFX]

Yes we need to.
