Maybe a stream could be introduced with something like:

To be clear, I'm not proposing exposing the system's filesystem to the
guest.

It's really just a way of getting name=value pairs.  If there is a
different way to do this then that's fine.  Ideally, to fit with
SeaBIOS' current code, there would be a way to obtain the size and
data for a given "name" along with an ability to iterate through the
list of "names" available.
