This information is just some numeric values, indicating some wanted behaviour. I thought of using a header file to keep these values aligned between the user space tool and u-boot. This header is provided by a library.  Including it into the user space tool is straight forward, but into u-boot does seem complicated, as the build system is not meant to include external libraries. Is there a preferred way to do this kind of alignment or a suggestion on how to handle this?

How about writing it into the linux device-tree. 'bootstage' does this in the same way if I remember correctly.
