That's a good point, not sure to which level we need to enable all 
modules of supported hardware. I added RFKILL and RFKILL_GPIO as it was 
not obvious to me that those need to be enabled to get proper WiFi 
support. Also those are tiny drivers compared to the RTW89 driver.
OTOH, I see that this driver is enabled for the loongarch architecture, 
so maybe we can do the same for riscv..

Paul, any idea about that, any policy?

Yes same, so I also didn't notice.
