+/** @file
+ Support routines for memory allocation routines based
+ on SMM Services Table services for SMM phase drivers, with memory profile support.
+
+ The PI System Management Mode Core Interface Specification only allows the use
+ of EfiRuntimeServicesCode and EfiRuntimeServicesData memory types for memory
+ allocations through the SMM Services Table as the SMRAM space should be
+ reserved after BDS phase. The functions in the Memory Allocation Library use
+ EfiBootServicesData as the default memory allocation type. For this SMM
+ specific instance of the Memory Allocation Library, EfiRuntimeServicesData
+ is used as the default memory type for all allocations. In addition,
+ allocation for the Reserved memory types are not supported and will always
+ return NULL.
