Good day,
I have been wondering if any sort of "official" documentation exists for the mailbox property interface that is used to communicate with the firmware? So far I've only found two sources:
1) The firmware driver source code that lists all the functions but, unfortunately, without much documentation, and not all of these functions are used in the code:
https://github.com/raspberrypi/linux/bl ... firmware.h
2) The wiki page that documents some of the functions but sadly, far from all of them:
https://github.com/raspberrypi/firmware ... -interface
Is there anything else available?
Kind regards,
Robert
