wdenk 27b207fd0a * Implement new mechanism to export U-Boot's functions to standalone
applications: instead of using (PPC-specific) system calls we now
  use a jump table; please see doc/README.standalone for details

* Patch by Dave Westwood, 24 Jul 2003:
  added support for Unity OS (a proprietary OS)
