+Entry: u-boot-tpl-nodtb: TPL binary without device tree appended
+----------------------------------------------------------------
+
+Properties / Entry arguments:
+    - filename: Filename to include (default 'tpl/u-boot-tpl-nodtb.bin')
+
+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.
