In UEFI-related questions, the UEFI specification has a fair chance to
provide useful information.

Please refer to "3.1.3 Load Options" in the UEFI v2.6 spec, available
for download from <http://www.uefi.org/specifications>.

Locating the matching structure definition in the edk2 tree is left as
an exercise to the reader ;)
