+  Initialize the memory where the initial stacks will reside
+
+  This memory can contain the initial stacks (Secure and Secure Monitor stacks).
+  In some platform, this region is already initialized and the implementation of this function can
+  do nothing. This memory can also represent the Secure RAM.
+  This function is called before the satck has been set up. Its implementation must ensure the stack
+  pointer is not used (probably required to use assembly language)
