/**
* @defgroup SystemInit System Initialization
*
* @brief System initialization procedure.
*
* When RT-Thread operating system starts up, the basic operating system facility
* initialization routines must be invoked.
*
* The suggested initialization sequence is:
*
* - initialize device hardware
* rt_hw_board_init();
*
* User can put the low level hardware initialization in this function, such as
* DDR memory setting, pinmux setting, console device setting etc.
*
* - show version
* rt_show_version();
*
* - initialize system tick
* rt_system_tick_init();
*
* - initialize kernel object [deprecated]
* rt_system_object_init();
*
* - initialize timer system
* rt_system_timer_init();
*
* - initialize system heap memory
* rt_system_heap_init(__bss_end, __end_of_memory);
*
* - initialize module system
* rt_system_module_init();
*
* - initialize scheduler system
* rt_system_scheduler_init();
*
* - initialize application
* rt_application_init();
*
* - initialize system timer thread
* rt_system_timer_thread_init();
*
* - initialize idle thread
* rt_thread_idle_init();
*
* - start scheduler
* rt_system_scheduler_start();

/**
