If I gather correctly, it works but so does the one found in

FreeBSD-14.0-CURRENT-arm64-aarch64-RPI-20210311-15565e0a217-257277.img

? In other words, the material from

fbsd-rpi4-u-boot2021-04-klaus/files/u-boot.bin/download

works but is not required to make the RPi4B work?

Be very careful with referencing "latest" start4.elf and
the like because folks could easily interpret such to be
something like (using start4.elf as an example):

https://github.com/raspberrypi/firmware/blob/master/boot/start4.elf

that can change on a regular basis and is far from guaranteed
to be a version that works for FreeBSD use. (In recent months
such usually has not worked. Even tagged versions need not
work for FreeBSD use, as was true for FreeBSD tried to use
some in the range 1.20210104 through 1.20210201 .)

My guess here is that you are referring to materials from the
most recent sysutils/rpi-firmware port. Those are (for now)
based on somewhat older RPi* materials. Using start4.elf as
an example, sysutils/rpi-firmware is based on, in part,

https://github.com/raspberrypi/firmware/blob/1.20210303/boot/start4.elf

If one does find materials in master that work and wants to
refer to them, it is best to find what master translates to
at the time and refer to that specifically, for example:

https://github.com/raspberrypi/firmware/tree/0591568b29a724de406aa737fc8e13f68c423f3f

(One has to look at the commits history to figure out
such an absolute untagged reference.)
