  28   Initialize the memory where the initial stacks will reside
  29
  30   This memory can contain the initial stacks (Secure and Secure Monitor stacks).
  31   In some platform, this region is already initialized and the implementation of this function can
  32   do nothing. This memory can also represent the Secure RAM.
  33   This function is called before the satck has been set up. Its implementation must ensure the stack
  34   pointer is not used (probably required to use assembly language)
