Linux has its own dts/dtsi/... sources instead of using the .dtb files
from the RPi folks, not directly based on any vintage of the RPi .dtb
files if I understand right. As I understand, ubuntu is based on the
linux materials for producing .dtb files and so is likely not a full
match to older rpi .dtb files either. They continue to update the
.dtb's that they distribute, without also updating the start*.elf or
fixup*.dat files.
So far as I know, FreeBSD has been targeting support of some vintage
of the RPi materials, including .dtb files. That is what
sysutils/rpi-firmware is about. So the status relative to linux .dtb
files is likely normally-unknown.
I've not set up a USB3 SSD ubuntu 2020.04.1 (yet?), just a microsd
card one. I use apt to update the ubuntu microsd card once and a while.
It's /boot/firmware/ from a recent update currently looks like:

(I try to remember to do things in a way that preserves
the original file dates. But, whatever update procedures
do, I do not override.)
One thing of note is the use of an "overlay_map.dtb".
Without that things would likely be broken.
Notably the start*.elf and fixup*.dat files all predate
2020-Aug-20 by a fair amount. ("USB MSD boot also requires
the firmware from Raspberry Pi OS 2020-08-20 or newer.")
But ubuntu need not have used a tagged release at all
so it is not obvious just what vintage the start* and
fixup* files are from.
So, for now, ubuntu likely does not claim support of the
critical release (general release) of the USB MSD ability
for the RPI4 (even given modern enough eeprom contents
are present).
So far, I've never tried to have FreeBSD use any of these
materials --or any materials from ubuntu.

I've not yet tried a combination that uses a u-boot from the USB3
SSD (no microsd card) and gets anywhere near that far along on any
RPi4B (4 GiByte or 8 GiByte).
I've only gotten u-boot to boot RPi4B FreeBSD completely when
u-boot and the FreeBSD kernel were both from the microsd card.
(With the FreeBSD kernel in place, I can then have the later
stages use the USB3 SSD instead --and that is what I normally
do.) But for this to work I've had to use older start* and
fixup* files.
