/**
* @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.
