New Revision: 237023
URL: http://svnweb.FreeBSD.org/socsvn/?view=rev&rev=237023

Log:
  Results of some exploration.  The end result of this is a better
  understanding of how to build EFI applications using the build tools.
  
  I've also done a fair amount of exploring the EFI API, though that can't be
  reflected in actual code changes.
