You may find the full documentation about Kconfig here: https://www.kernel.org/doc/Documentation/kbuild/kconfig-language.txt > As I have seen, the KConfig file in the board specific folder only > contains general information like the vendor and board name. Yes, for a board maintainer in U-Boot this pretty much jsut boils down to adding a Kconfig file along your board files e.g. like [1]. And then just like you already found out there needs to be a default configuration file e.g. like [2]. This one may be created as follows: make savedefconfig Which saves a minimal configuration to a file called defconfig. > I would really appreciate a helpful answer that brings me further in > my school project. Of course further migration work you may want to tackle is driver model (DM) and/or device tree enablement. Should you have any further questions you know where to ask (;-p).
