This change allows to change the top of the System Memory that was hardcoded by: FixedPcdGet64 (PcdSystemMemoryBase) + FixedPcdGet64 (PcdSystemMemorySize) It allows to add support when the Trusted Firmware reserves the top of the System Memory as Trusted. The size of this region might not be known in advance. Note: The reason why the start of the System Memory has not been made dynamic is because the early code calculates where to place the stack from the top of the System Memory. So there is no need to make the start of the System Memory a dynamic value at the early stage of the boot phase.
