Here is the reference to you. You could get the final one from fathi's
build script file.

 # apt-get update
 # apt-get install grub-efi-arm64-bin
 # mkdir -p /boot/grub
 # echo 'configfile (hd0,gpt6)/grub/grub.cfg'  /boot/grub.configfile
 cat << EOF  /boot/grub/grub.cfg
 set default="0"
 set timeout=10

 menuentry 'HiKey' {
 insmod ext2
 insmod fat
 insmod part_gpt
 insmod part_msdos
 set root='hd0,gpt6'
 linux /Image console=ttyAMA3,115200
 root=/dev/disk/by-partlabel/system ro rootwait
 efi=noruntime
 initrd /initrd.img
 devicetree /hi6220-hikey.dtb
 }
 EOF

 # grub-mkimage \
 --verbose \
 --config=/boot/grub.configfile \
 --output=grubaa64.efi \
 --format=arm64-efi \
 --prefix='(hd0,gpt6)/grub' \
