First, it takes the DTB from U-Boot, then it creates signed FIT kernel image and places kernel key into the DTB. After that it executes: make EXT_DTB=/path/to/dtb/with/kernel/key Despite the fact that in the documentation all examples with EXT_DTB use only single DTB, the patch allows pass many DTB files separated by spaces, e.g.: make EXT_DTB="/path1/to/1.dtb /path2/to/2.dtb" The first DTB from the list become default configuration.
