6 * @brief Standard system startup.
7 *
8 *  This is the C entry point for ALL RTEMS BSPs.  It is invoked
9 *  from the assembly language initialization file usually called
10 *  start.S.  It provides the framework for the BSP initialization
11 *  sequence.  For the basic flow of initialization see RTEMS C User's Guide,
12 *  Initialization Manager.
13 *
14 *  This style of initialization ensures that the C++ global
15 *  constructors are executed after RTEMS is initialized.
16 *  Thanks to Chris Johns <cjohns@plessey.com.au> for the idea
17 *  to move C++ global constructors into the first task.
