29  Call at the beginning of the platform boot up
30
31  This function allows the firmware platform to do extra actions at the early
32  stage of the platform power up.

34  Note: This function must be implemented in assembler as there is no stack set up yet

41  Initialize the memory where the initial stacks will reside
42
43  This memory can contain the initial stacks (Secure and Secure Monitor stacks).
44  In some platform, this region is already initialized and the implementation of this function can
45  do nothing. This memory can also represent the Secure RAM.
46  This function is called before the satck has been set up. Its implementation must ensure the stack
47  pointer is not used (probably required to use assembly language)
