+This file should contain the bin_hdr generated by the original Marvell
+U-Boot implementation. As this is currently not included in this
+U-Boot version, we have added this placeholder, so that the U-Boot
+image can be generated without errors.
+
+If you have a known to be working bin_hdr for your board, then you
+just need to replace this text file here with the binary header
+and recompile U-Boot.
+
+In a few weeks, mainline U-Boot will get support to generate the
+bin_hdr with the DDR training code itself. By implementing this code
+as SPL U-Boot. Then this file will not be needed any more and will
+get removed.
