According to a page that hasn't been updated for a while
(https://wiki.freebsd.org/SDIO) work is in progress on Broadcom wireless
drivers for the Raspberry Pi 3 and 4. I'm supposed to start by building the
GENERIC-MMCCAM kernel. A CAM device will then appear which I can then use
camcontrol to talk to. I built the kernel and booted it on my Pi 3B+, which
has a Broadcom 43455/6 according to Linux. All camcontrol finds is the mini
SD card. I see only one call to sdhci_init_slot in bcm2835_sdhost.c so maybe
that's the problem. It supports exactly one SDIO device, a memory card.
Any thoughts? Is it worth thinking about the wireless chip or is it just too
much work?

As you got no answer from somebody who knows more about this than I do I will
try to give some pointers.
Here you can search through the history of the mailinglist.

Look for WiFi/SDIO/RPI kind of subjects.
The latest I found about this subject:
https://lists.freebsd.org/archives/freebsd-arm/2020-October/022626.html.
I don't know anything about the current state. But a USB-WiFi dongle might be a
reasonable shortcut.
I'll cc the Bjoern from this e-mail. @bjoern: do you have a status update?
Regards,
Ronald.
Oh, here is another update:
https://lists.freebsd.org/archives/freebsd-arm/2020-February/021340.html which
points to
https://lists.freebsd.org/pipermail/freebsd-wireless/2020-February/008985.html
So, somebody on the freebsd-wireless might know about it also,
IMHO It would be nice if the work-in-progress of this driver was shared in a
known place so more people could help.
Regards,
Ronald.
