Waveshare bar LCD screen with Bananapi M2 Zero ?

[wanderer]

After trying different distro for the BPI M2 Zero, I installed Armbian, and it works great with a standard 16:9 screen. Now I would like to use a bar LCD (Waveshare 7.9 inches); but the setup instructions are for RPI, not for Armbian, so I am not sure how you set up a screen that is not default (And I exclude that I can just plug in the screen and it will magically work.

I am not using X interface since the BPI is quite slow, so I am in terminal. Thanks
