Called at the early stage of the Boot phase to know if the memory has already been initialized
Running the code from the reset vector does not mean we start from cold boot. In some case, we
can go through this code with the memory already initialized.
Because this function is called at the early stage, the implementation must not use the stack.
Its implementation must probably done in assembly to ensure this requirement.

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)
