This means, a firmware file isn't found, because it is searched under
a different name.

You should have:

-r--r--r--  1 root  wheel  1863 Mar 28 17:45 libdata/firmware/if_bwfm/brcmfmac43455-sdio.raspberrypi,4-model-b.txt

and need to create a symlink like:

cd /libdata/firmware/if_bwfm
ln -s brcmfmac43455-sdio.raspberrypi,4-model-b.txt "brcmfmac43455-sdio.Raspberry Pi 4 Model B.txt"

Reason is that the platform is canonically named "raspberrypi,4-model-b"
but UEFI chose "Raspberry Pi 4 Model B" instead.
