I had always assumed that the top-level compatible string would be a sort of "checksum" over the rest of the content. Which, admittedly, makes it kind of redundant. Compatibility could mean a lot of things. Does it mean any kernel/DTB compatible with one device could run on any device derived from it? Does compatibility mean it needs to provide full functionality or is it still compatible if it runs at a reduced feature set but doesn't "break" otherwise?
