If we need this for other reasons, it should not > be an architecture specific option. We want the BUILTIN_DTB for some boards and they don't need change dtb at all. And I just follow other archs BUILTIN_DTB in their Kconfig. eg: xtensa, h8300, mips, nds32, sh, openrisc, arc ... I just keep this in Kconfig.debug and it's not a recommended method. Guo Ren
