Wifi not turning on with the new Raspberry Pi 400 #51

I just tried arpi-10 on the new Raspberry Pi 400, wifi won't turn on. Was hoping for it to work out of the box with an Rpi4 build but turns out it's not, I believe Raspberry Pi 400 has a newer chip than the Pi4

Coming from Arch Linux ARM with the same issue. In my case (from running dmesg | grep mmc1 mmc1 being the wifi chip) it seems that it tries to load the file /lib/firmware/brcm/brcmfmac43456-sdio.bin but that file doesn't exist in the distro.

After I copied the Raspberry Pi 400 firmware files (/lib/firmware/brcm/brcmfmac43456-sdio.* ) from the latest official Raspberry Pi OS iso to my installation, wifi worked.

From what I see in this repo copying the firmware files to device_arpi_rpi4/firmware/brcm/ may also do the trick.

Wifi is now working with arpi-12 build.
