*
|
|
* @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.
