(I became curious and so looked around some more
at the modern context.)
I suppose a more direct note is that
FreeBSD-13.0-BETA4-arm-armv7-GENERICSD.img put
on a microsd card looks like:

# find /mnt/EFI/ -print
/mnt/EFI/
/mnt/EFI/BOOT
/mnt/EFI/BOOT/bootarm.efi
(Nothing for efi/boot/startup.nsh . Also a capitalization
style difference vs. what I see on the OverDrive 1000 and
MACCHIATOBin Double Shot that I have in use
[ efi/boot/BOOTaa64.efi ].)
So it looks like EFI/BOOT/bootarm.efi exists even when it is
not used, when the context is based on a release or snapshot
GENERICSD for armv7. (I've not identified an armv7
EFI/BOOT/bootarm.efi use but there may well be some for all
I know.)
The above also points out u-boot.bin and u-boot.img contexts,
as well as the boot.scr / ubldr.bin ones. When one of these
are used, EFI/BOOT/bootarm.efi is not used, even when present.
As for aarch64 . . .
Looking at FreeBSD-13.0-BETA4-arm64-aarch64-mini-memstick.img
shows (when expanded to a microsd card):
# gpart show -p /dev/mmcsd1
=> 3 679832 mmcsd1 GPT (30G) [CORRUPT]
3 66584 mmcsd1p1 efi (33M)
66587 613248 mmcsd1p2 freebsd-ufs (299M)
# find /mnt/ -print
/mnt/
/mnt/EFI
/mnt/EFI/BOOT
/mnt/EFI/BOOT/bootaa64.efi
(Again: capitalization and startup.nsh differences
compared to what I see on the OverDrive 1000 and
MACCHIATObin Double Shot.)
RPI, PINE64, PINE64-LTS, ROCK64, and ROCKPRO64
have images for aarch64.
Looking at RPI:
# gpart show -p /dev/mmcsd1
=> 63 62333889 mmcsd1 MBR (30G)
63 2016 - free - (1.0M)
2079 102312 mmcsd1s1 fat32lba [active] (50M)
104391 6187041 mmcsd1s2 freebsd (3.0G)
6291432 56042520 - free - (27G)
So, not GPT.
# find /mnt/ -print
/mnt/
/mnt/EFI
/mnt/EFI/BOOT
/mnt/EFI/BOOT/bootaa64.efi
/mnt/dtb
. . . (dtb substructure omitted) . . .
/mnt/README
/mnt/u-boot.bin
/mnt/armstub8.bin
/mnt/armstub8-gic.bin
/mnt/bootcode.bin
/mnt/fixup_cd.dat
/mnt/fixup_db.dat
/mnt/fixup_x.dat
/mnt/fixup.dat
/mnt/LICENCE.broadcom
/mnt/start_cd.elf
/mnt/start_db.elf
/mnt/start_x.elf
/mnt/start.elf
/mnt/fixup4.dat
/mnt/fixup4cd.dat
/mnt/fixup4db.dat
/mnt/fixup4x.dat
/mnt/start4.elf
/mnt/start4cd.elf
/mnt/start4db.elf
/mnt/start4x.elf
/mnt/bcm2710-rpi-2-b.dtb

[all]
arm_64bit=1
dtparam=audio=on,i2c_arm=on,spi=on
dtoverlay=mmc
dtoverlay=disable-bt
device_tree_address=0x4000
kernel=u-boot.bin
[pi4]
hdmi_safe=1
armstub=armstub8-gic.bin
So it has EFI/BOOT/bootaa64.efi but is a
u-boot.bin context in operation: bootaa64.efi
is unused unless changes are made.
By contrast, ROCK64 does use GPT and has just:
# find /mnt/ -print
/mnt/
/mnt/EFI
/mnt/EFI/BOOT
/mnt/EFI/BOOT/bootaa64.efi
/mnt/dtb
. . . (dtb substructure omitted) . . .
(spans more than ROCK64)
and EFI/BOOT/bootaa64.efi is used.
(I'll not look at the other 3 --or at
riscv64 or the like.)
