PS1: 
This currently doesn't work in the doc.coreboot.org container as Doxygen needs to be able to write its output somewhere, and the container mounts the tree as RO at /`/data-in` with `Documentation/_build/` being mounted RW at `/data-out`. Doxygen doesn't seem to have a flag to override the output directory in the Doxyfile so there isn't a trivial way to point it to `/data-out`.
