For reference this is my untested hook for the Efika..

efikamx_flash_kernel() {
 tmp=$(tempfile)
 printf "Generating kernel u-boot image... " >&2
 mkimage -A arm -O linux -T kernel -C none -a 0x90008000 \
  -e 0x90008000 -d $kfile "$tmp.uImage" >&2 1>/dev/null
 echo "done." >&2

 if [ -e /boot/uImage-${kvers} ]; then
  mv /boot/uImage-${kvers} /boot/uImage-${kvers}.bak
 fi
 mv $tmp.uImage /boot/uImage-${kvers}
 rm -f "$tmp.uImage"

 if [ -e ${ifile} ]; then
  printf "Generating initrd u-boot image... " >&2
