+  Perform CPU specific actions required to migrate the PEI Services Table 
+  pointer from temporary RAM to permanent RAM.
+
+  For IA32 CPUs, the PEI Services Table pointer is stored in the 4 bytes 
+  immediately preceding the Interrupt Descriptor Table (IDT) in memory.
+  For X64 CPUs, the PEI Services Table pointer is stored in the 8 bytes 
+  immediately preceding the Interrupt Descriptor Table (IDT) in memory.
+  For Itanium and ARM CPUs, a the PEI Services Table Pointer is stored in
+  a dedicated CPU register.  This means that there is no memory storage 
+  associated with storing the PEI Services Table pointer, so no additional 
+  migration actions are required for Itanium or ARM CPUs.
