    Properties / Entry arguments:
        - spl-dtb: Controls whether this entry is selected (set to 'y' or '1' to
            select)

    This is a section containing the U-Boot binary, BSS padding if needed and a
    devicetree. Using this entry type automatically creates this section, with
    the following entries in it:

       u-boot-spl-nodtb
       u-boot-spl-bss-pad
       u-boot-dtb

    Having the devicetree separate allows binman to update it in the final
    image, so that the entries positions are provided to the running U-Boot.

    This entry is selected based on the value of the 'spl-dtb' entryarg. If
    this is non-empty (and not 'n' or '0') then this expanded entry is selected.
