+/**
+ * @file
+ *
+ * @ingroup bsp_bootcard
+ *
+ * @brief Standard system startup.
+ *
+ *  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.  For the basic flow of initialization see RTEMS C User's Guide,
+ *  Initialization Manager.
+ *
+ *  This style of initialization ensures that the C++ global
+ *  constructors are executed after RTEMS is initialized.
+ *  Thanks to Chris Johns <cjohns@plessey.com.au> for the idea
+ *  to move C++ global constructors into the first task.
