Hi, Is there any restriction (official or otherwise) in porting (mostly copying & renaming) files from the SiFive gitihubs (e.g. [GitHub - sifive/freedom-u-sdk: Freedom U Software Development Kit (FUSDK)](https://github.com/sifive/freedom-u-sdk) & [GitHub - sifive/meta-sifive: SiFive OpenEmbedded / Yocto BSP Layer](https://github.com/sifive/meta-sifive)) to other Linux distributions? Thanks. ---

The intent is that all of the code is open source, and most of it has been upstreamed. Everything required for the boards to work should be upstream. I think only some of the optional stuff and local config stuff isn’t upstream. If you need patches for a specific kernel or u-boot version that isn’t upstream then you can grab them from freedom-u-sdk if theyhappen to be there. Borrowing patches should be fine. You should eventually move to the upstream stuff though. ---

A notable set of patches that aren’t upstream yet but are not fluff is the case fan / PWM bits 👀
