   *   up_initialize will be called once during OS
   *   initialization after the basic OS services have been
   *   initialized.  The architecture specific details of
   *   initializing the OS will be handled here.  Such things as
   *   setting up interrupt service routines, starting the
   *   clock, and registering device drivers are some of the
   *   things that are different for each processor and hardware
   *   platform.
   *
   *   up_initialize is called after the OS initialized but
   *   before the init process has been started and before the
   *   libraries have been initialized.  OS services and driver
   *   services are available.
