No wlan0 on DK1 I just received.

I have a pair of DK1 boards I just received that I wanted to get working with wifi direct, but neither even can show a wlan0 interface. In the past I have used a DK2 with buildroot and got the wlan0, and a coworker used stock yocto build on the DK2 and said wlan0 was there too. Is there some problem with the DK1?

wlan0: Failed to initialize driver interface

This is the shipped SD version with 4.19 kernel. I also tried my own Dunfell build with kernel 5.4, same problem with no wlan0.

Looking through some other comments I noticed it mentioned there is no wifi chipset on the DK1. This might explain it!
