      1. What happened?

With my RockPi-S I go to `armbian-config` overlay selection and I enable `s0-ext-antenna` however this shows up while booting:

```
Applying kernel provided DT overlay rk3308-s0-ext-antenna.dtbo
failed on fdt_overlay_apply(): FDT_ERR_NOTFOUND
226 bytes read in 6 ms (36.1 KiB/s)
```
Doing git archeology this happens because the dts for `s0-ext-antenna` target symbols like `board_antenna` that are defined in `board-rocks0-0001-deviceTree.patch` but not in `rk3308-rock-pi-s.dts` (file in upstream linux).
However looking at the hardware the wifi setup for the rock-pi-s0 and rock-pi look different:

On the Rock-Pi-S0, we can clearly spot an RF Switch IC (tiny black SMD component in the following screenshot), with impedance matched traces going to the Ceramic antenna, the ufl connector and the SOM:

However on the Rock-Pi-S there is no such switch, or built-in ceramic antenna to begin with, we can spot the Realtek WiFi+BT IC, a π matching network and impedance matched traces straight to the antenna connector:
Critically I do not see an RF Switch IC or a builtin ceramic antenna.

So if my understand is correct this file should not be compiled to begin with given there is no built-in antenna to begin with on the Rock Pi S.
