 * @date      19. Mar. 2010
 * @brief     STM32F10x Medium Density Devices vector table for GNU toolchain.
 *            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 
 *                - Branches to main in the C library (which eventually
 *                  calls main()).
 *            After Reset the Cortex-M3 processor is in Thread mode,
 *            priority is Privileged, and the Stack is set to Main.

/* Modified by Martin Thomas
   - to take VECT_TAB_RAM setting into account, also see the linker-script
   - to avoid warning "ISO C forbids initialization between function pointer and 'void *'".
   - added optional startup-delay to avoid unwanted operations while connecting with
     debugger/programmer
   - tested with the GNU arm-eabi toolchain as in CS G++ lite Q1/2009-161
   - minor modification in .data copy to avoid copy while "run from RAM"
     during debugging

* mthomas: If been built with VECT_TAB_RAM this creates two tables:
* (1) a minimal table (stack-pointer, reset-vector) used during startup
*     before relocation of the vector table using SCB_VTOR
* (2) a full table which is copied to RAM and used after vector relocation
*     (NVIC_SetVectorTable)
* If been built without VECT_TAB_RAM the following comment from STM is valid:
* The minimal vector table for a Cortex M3.  Note that the proper constructs
* must be placed on this to ensure that it ends up at physical address
* 0x0000.0000.
