LCD Display on Raspberry PI 3B

I currently have a 3.5" TFT dispay with a SPI interface (PI display) that i am trying to get to run in openwrt on the raspberry PI 3B as my primary display. the driver IC is ILI9486. what is involved to do this considering i'm a newb?

You could check if lcd4linux supports your display and use the display to show status information or whatever you would like displayed. Remember that OpenWrt does not have a GUI, so you won't see anything unless you configure it explicitly.
