I see. The configuration was added with the initial commit 05284b64d00f by Patrick Rudolph. Maybe he just forgot to add a proper fmd file. Though, the fmd file highly depends on the users use case and can be configured with Kconfig by themselves. So adding one just fulfills some use cases and allows it to be built with Vboot support.

@Patrick: Did you test the board with Vboot? Do you have a proper fmd file for it?
