Thanks for pointing out this part. I should remove CONFIG_DEFAULT_FDT_FILE
actually. Because environment variable fdt_file does not impact what
fdt to use for
booting OS. The dtb file is specified by the argument of FIT
configuration feed to
bootm command in verified boot case with using FIT, such as
"bootm 0x83200000#conf at imx7d-pico.dtb"
