We already have guides on how to enable UART. It is up to the device implementers to handle drivers. Please contact the authors of the projects and point them here. All of our stuff is based on standard upstream Linux. If their code is written properly, it should work. If not, then they need to be the ones who fix it.
We cannot be engineering support for xyz device manufacturer’s products. We can only build our stuff to standards and hope that others follow standards and maintain their code base.
