Forked Marlin Repositories

The two main repositories are forked from Marlin/Marlin (Firmware) and Marlin/Configurations. This way we can update our codebase with a fork sync, and create pull requests back.

Unique branches with the “ecf-” prefix are used to host our code and keep it separate from upstream

We follow the branch naming pattern ecf-[model]-[mainboard]
