- Support routines for memory allocation routines based on SMM Core internal functions.
-
- The PI System Management Mode Core Interface Specification only allows the use
- of EfiRuntimeServicesCode and EfiRuntimeServicesData memory types for memory
- allocations 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.
