+
+    This is the U-Boot TPL binary, It does not include a device tree blob at
+    the end of it so may not be able to work without it, assuming TPL needs
+    a device tree to operate on your platform. You can add a u-boot-tpl-dtb
+    entry after this one, or use a u-boot-tpl entry instead (which contains
+    both TPL and the device tree).
+
+    TPL can access binman symbols at runtime. See:
+
+        'Access to binman entry offsets at run time (symbols)'
+
+    in the binman README for more information.
+
+    The ELF file 'tpl/u-boot-tpl' must also be available for this to work, since
+    binman uses that to look up symbols to write into the TPL binary.
