Hi,

as far as I remember, the foundation paid some devs for the sdio implementation.
But they stopped developing the brcmfmac-Wifi-drivers for some unknown reason.
The last time I looked into it on the Pi : sdio didn’t work for a simple reason : 
There was a missing overlay in config.txt .
That’s one of the reasons why e.g. Mark and me often take focus on 
the msdos partitions environment, u-boot etc.
Sometimes discussions like this sound weird but all has to do with the other :-)
For now we should have sdio working on the Pi with the MMCCAM kernel.
OpenBSD used their standard SD-driver IIRC so the next step 
would be to port parts of OpenBSD`s driver to the fbsd-sdio …
somewhat superficially described but combine forces with some people here 
We could have a good starting point to work on a driver, with or without the fbsd-foundation.
But there should be at least one FreeBSD developer who says:
Yes, that’s a good path to go if you guys can manage that …
I also think of IOT things like LoraWan and so on but having the onboard Wifi for brcmfmac should be a 
good starting point, then BT and so on...but it's going to be a pretty dirty job :-)

Above Information without guarantee as I am not a FreeBSD member.
