+Image description format
+------------------------

+The binman node is called 'binman'. An example image description is shown
+below:

  binman {

          filename = "u-boot-sunxi-with-spl.bin";

          pad-byte = <0xff>;

          blob {

                  filename = "spl/sunxi-spl.bin";

          };

          u-boot {

                  pos = <CONFIG_SPL_PAD_TO>;

          };

  };

Oh my, finally CONFIG_ in device tree.
If CONFIG_SPL_OF_CONTROL is enabled, SPL can parse "/binman/u-boot/pos" property
to know which offset address SPL should load U-Boot proper from,
then remove CONFIG_SPL_PAD_TO.
Otherwise, I have no idea to avoid this.
Yes we can do that. but in any case we need this CONFIG in the DT. I
think this CONFIG (or one depending on it) is also used in the build
to provide the link address for U-Boot.
