I am using nanobsd with RPi3. Never tried RPi4. I did some customization 
to the nanobsd scripts and configuration to get it working though.

Last time I rebuilt my image was in mid december. I'm going to build a 
new image in the next pair of weeks.

Is the problem limited to the boot code?

I have this code to create that partition:

populate_boot_part ( ) (
     MNT=$1

     UBOOT_DIR="/usr/local/share/u-boot/${NANO_BOOT_PKG}"
     FIRMW_DIR="/usr/local/share/rpi-firmware"
     FIRMO_DIR="${FIRMW_DIR}/overlays"

     # Required files
     UBOOT_FILES="README u-boot.bin"
     DTB="bcm2710-rpi-2-b.dtb bcm2710-rpi-3-b.dtb 
bcm2710-rpi-3-b-plus.dtb bcm2710-rpi-cm3.dtb bcm2711-rpi-4-b.dtb"
     OVERLAYS="mmc.dtbo pwm.dtbo disable-bt.dtbo"
     DTB_FILES="armstub8.bin armstub8-gic.bin bootcode.bin fixup_cd.dat \
         fixup_db.dat fixup_x.dat fixup.dat LICENCE.broadcom \
         start_cd.elf start_db.elf start_x.elf start.elf \
         fixup4.dat fixup4cd.dat fixup4db.dat fixup4x.dat start4.elf \
         start4cd.elf start4db.elf start4x.elf ${DTB}"

     for _F in ${UBOOT_FILES}; do
         cp ${UBOOT_DIR}/${_F} ${MNT}/${_F}
     done
     for _F in ${DTB_FILES}; do
         cp ${FIRMW_DIR}/${_F} ${MNT}/${_F}
     done
     cp -p ${FIRMW_DIR}/config_arm64.txt ${MNT}/config.txt
     mkdir -p ${MNT}/overlays
     for _F in ${OVERLAYS}; do
         cp -p ${FIRMO_DIR}/${_F} ${MNT}/overlays/${_F}
     done

     mkdir -p ${MNT}/EFI/BOOT
     cp -p ${NANO_WORLDDIR}/boot/loader_lua.efi \
         ${MNT}/EFI/BOOT/bootaa64.efi

     cp -R ${NANO_WORLDDIR}/boot/dtb ${MNT}

     # tell loader what partition to startup from
     mkdir -p ${MNT}/EFI/freebsd
     echo "rootdev=disk0s3a" >${MNT}/EFI/freebsd/loader.env
)

Hope this helps.
