Regarding the built-in wifi, in current I believe you don't need to
change the fdt, but you do need to rebuild the kernel with "bwfm* at
sdmmc?" in the config, and you need to grab the correct firmware
(differs slightly between different Pi models) and put it in
/libdata/firmware/if_bwfm/.

I am pretty sure it won't work on 9 even if you rebuild, as it seems
the key bits of if_bwfm_sdio.c didn't make it in time (from a quick
look at CVS).

Wifi works out of the box on my 0W using ebijun's pre-built images, as
it incorporates all the above changes (see 
https://github.com/ebijun/NetBSD/blob/master/RPI/RPIimage/Image/README#L19
 )

With regards,
