+#
+# The following example assumes you use a Gembird power switch connected
+# through USB to be able to power cycle the board you want to fel boot. You
+# need the sispmctl package and use 'sispmctl -s' to get the ID of your 
+# power switch.
+
+fel_pre_load() {
+	# power cycle socket 1 of Gembird power switch
+	sispmctl -D01:01:51:23:cb -q -f1
+	# 5 seconds delay since PSUs don't like be being power cycled too fast
+	sleep 5
+	sispmctl -D01:01:51:23:cb -q -o1
+	# 3 seconds delay since the SoC has to initialise
+	sleep 3
+} # fel_pre_load
+
+fel_post_prepare() {
+	# currently empty - sun8i-default tweaks were converted into u-boot patches
+	echo "calling fel_post_prepare()"
+} # fel_post_prepare
