+Booting Firmware Update images
+-------------------------------------
+
+When Firmware Update (FWU) is enabled there are at least 2 new images
+that have to be loaded, the Non-Secure FWU ROM (NS-BL1U), and the
+FWU FIP.
+
+Juno
+~~~~
+
+The new images must be programmed in flash memory by adding
+an entry in the ``SITE1/HBI0262x/images.txt`` configuration file
+on the Juno SD card (where ``x`` depends on the revision of the Juno board).
+Refer to the `Juno Getting Started Guide`_, section 2.3 "Flash memory
+programming" for more information. User should ensure these do not
+overlap with any other entries in the file.

+    --data cluster0.cpu0="<path_to>/fwu_fip.bin"@0x08400000	[ns_bl2u_base_address]
