- - tpl-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-tpl-nodtb
- u-boot-tpl-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 'tpl-dtb' entryarg. If
- this is non-empty (and not 'n' or '0') then this expanded entry is selected.
