+  * @brief     Based on STM32F103xE's startup file.
+  *            This module performs:
+  *                - Set the initial SP
+  *                - Set the initial PC == Reset_Handler,
+  *                - Set the vector table entries with the exceptions ISR address
+  *                - Configure the clock system
+  *                - Configure external SRAM mounted on STM3210E-EVAL board
+  *                  to be used as data memory (optional, to be enabled by user)
+  *                - Branches to entry in the C library (which eventually
+  *                  calls main(), but entry() in RT-Thread).
+  *            After Reset the Cortex-M3 processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.
