There are no different firmware versions, so no links necessary.
The NVRAM files (*.txt) on the other hand are different, e.g.:
-r--r--r-- 1 root wheel 1863 Mar 7 15:34 /libdata/firmware/if_bwfm/brcmfmac43455-sdio.raspberrypi,4-model-b.txt
-r--r--r-- 3 root wheel 1864 Mar 7 15:34 /libdata/firmware/if_bwfm/brcmfmac43455-sdio.raspberrypi,3-model-b-plus.txt
< # Raspberry Pi 4 Model B
> # Raspberry Pi 3 Model B+
N.B. current firmware as delivered with Linux doesn't work at all and
also requires a third file (*.clm_blob) for regulatory parameters.
