* The SystemInit() is a standard CMSIS function called during system startup.
* It is meant to perform low level hardware setup such as configuring PLLs. In
* the case of SmartFusion these hardware setup operations are performed by the
* chip boot which executed before the application started. Therefore this
* function does not need to perform any hardware setup.
void SystemInit(void);
* The SystemCoreClockUpdate() is a standard CMSIS function which can be called
* by the application in order to ensure that the SystemCoreClock global
* variable contains the up to date Cortex-M3 core frequency. Calling this
* function also updates the global variables containing the frequencies of the
* APB busses connecting the peripherals and the ACE frequency.
