wtf is meta-partner-arduino?

This repository provides the building blocks to create a custom Linux operating system image for the Arduino Portenta X8, a powerful industrial-grade board. It's important to note right away that this project is deprecated and has been replaced by a newer official version, so anyone looking to use it should check the replacement instead. The project uses something called Yocto, which is a tool for creating custom Linux systems tailored to specific hardware. Think of Yocto as a kitchen that takes raw ingredients (software packages, configurations, and drivers) and bakes them into a finished operating system ready to run on a specific device. The "recipes" in this repository are essentially instructions that tell Yocto exactly which components to include and how to assemble them for the Portenta X8 board. This would be used by hardware developers or embedded engineers building products on top of the Portenta X8 platform, for example, someone creating an industrial IoT gateway, a robotics controller, or a custom edge computing device who needs a streamlined operating system with only the software their product actually requires, rather than a generic one-size-fits-all Linux distribution. The README doesn't go into much detail beyond pointing to broader documentation on building custom images, so the repository itself is really just one piece of a larger workflow rather than a standalone tool. Since this layer is being archived, anyone starting a new project should use the successor linked in the deprecation notice instead.
