Just an FYI.
Summary:
ubuntu has wifi-2.4ghz-coexistence and more
brcm,bcm2835-* compatible naming.
Details:
I used .dts files from : dtc -Idtb -Odts -s -o... ...
on FreeBSD to compare the ubuntu 2104 beta, fedora f34
beta, and sysutils/rpi-firmware bcm2711-rpi-4-b.dtb
files. The beta's are just what I happened to have
handy and are fairly recent.
f34 and rpi-firmware matched but ubuntu and
rpi-firmware showed:

So not much is different (up to live updates during
booting).
sysutils/rpi-firmware is currently based on materials from:
https://github.com/raspberrypi/firmware/tree/1.20210303/
Sufficiently modern snapshot image builds and 13.0-RC[3-5]
ones are based on that sysutils/rpi-firmware vintage as
well. The FreeBSD-13.0-RELEASE-arm64-aarch64-RPI.img.xz
build will be based on the same.
I'll note that a more recent (post-tagged) RPi*
firmware bundled in RPi4_UEFI_Firmware_v1.25.zip
shows:
