- *  A simple main which can be used on any embedded target.
+ *  This is the C entry point for ALL RTEMS BSPs.  It is invoked
+ *  from the assembly language initialization file usually called
+ *  start.S.  It provides the framework for the BSP initialization
+ *  sequence.  The basic flow of initialization is:
+ *
+ *  + start.S: basic CPU setup (stack, zero BSS) 
+ *    + boot_card
+ *      + bspstart.c: bsp_start - more advanced initialization
+ *      + rtems_initialize_executive_early
+ *        + all device drivers
+ *      + rtems_initialize_executive_late
+ *        + 1st task executes C++ global constructors
+ *        .... appplication runs ...
+ *        + exit
+ *     + back to here eventually
+ *     + bspclean.c: bsp_cleanup
  *
  *  This style of initialization insures that the C++ global
  *  constructors are executed after RTEMS is initialized.
