FreeBSD-14.2-RELEASE-arm64-aarch64-RPI.img contains the
u-boot from:

/usr/ports/sysutils/u-boot-rpi-arm64

and, so, also contains and should be used with a copy of:

/usr/local/share/rpi-firmware/config_arm64.txt

as config.txt :

# grep -rA1 config_arm64 /usr/src/release/
/usr/src/release/arm64/RPI.conf: chroot ${CHROOTDIR} cp -p ${DTB_DIR}/config_arm64.txt \
/usr/src/release/arm64/RPI.conf- ${FATMOUNT}/config.txt

/usr/local/share/rpi-firmware/config_rpi3.txt is for when:

/usr/ports/sysutils/u-boot-rpi3

is is use instead. No modern snapshot or release uses that:

# grep -r config_config_rpi3 /usr/src/release/
#

/usr/local/share/rpi-firmware/config_rpi_0_w.txt is for when:

/usr/ports/sysutils/u-boot-rpi-0-w

is is use instead. An rpi-0-w is not a arm64 / aarch64 system.

# grep -r config_rpi_0_w /usr/src/release/
#

config_rpi3.txt is likely not fully appropriate and
config_arm64.txt is likely what should be used. But
it was already in place as config.txt in:

FreeBSD-14.2-RELEASE-arm64-aarch64-RPI.img

FreeBSD-14.2-RELEASE-arm64-aarch64-RPI.img is for
all the aarch64 / arm64 RPi*'s that FreeBSD happens
to support. (RPi5's not being supported as stands.)
