*Preserve multiboot information structure*

Type: ``bool``

Help
====

.. code-block:: none

    Multiboot passes a pointer to an information structure to the
    kernel entry point. Some drivers (e.g., the multiboot framebuffer
    display driver) need to refer to information in this structure,
    and so set this option to preserve the data in a permanent location.

Direct dependencies
===================
