Subject: arm: dts: iot2050: Use the auto generator nodes for fdt
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ffbd5b29a4820a874520273c9140d7d125500af7;p=u-boot.git

arm: dts: iot2050: Use the auto generator nodes for fdt

Refactor according to the entry `fit: Entry containing a FIT` of
document tools/binman/README.entries.

As the generator uses the device tree name for the config description,
board_fit_config_name_match requires a small adjustment as well.
