+ * $LOG$
+ * 2019/7/20 - ROBIN KRENS     
+ * Initial version 
+ * 
+ * $DESCRIPTION$
+ * Linker file for Cortex-M3 STM32 based boards
+ * Boards have similar FLASH and SRAM ORIGINs
+ * LENGTHs differs of course.
+ * 
+ * _start flag is the first procedure to be 
+ * executed (linked to beginning of FLASH at 
+ * 0x08000000). The procedure should do some
+ * basic things, such as set up the stack and
+ * reset and hard fault handler (see start.asm)
+ * *
+ * _endofbss flag is used to calculate the end 
+ * of .bss and the start of (a possible) kernel
+ * heap
+ *
