This looks wrong. You should have either tools/bootloader or tools/bootImageRunner both not both. Also, you probably shouldn't need to modify GenerateInterfaceDeclarations.

If you can produce a minimal diff against git HEAD for what you're trying to do, I could take a look. IIRC I also have an example patch somewhere that adds a new syscall. I could use that to write some documentation in the user guide but I might need a few days to make time for that.
