2 | Support routines for memory allocation routines based \r | |
3 | on SMM Services Table services for SMM phase drivers.\r | |
4 | \r | |
5 | The PI System Management Mode Core Interface Specification only allows the use\r | |
6 | of EfiRuntimeServicesCode and EfiRuntimeServicesData memory types for memory \r | |
7 | allocations through the SMM Services Table. The functions in the Memory \r | |
8 | Allocation Library use EfiBootServicesData as the default memory allocation\r | |
9 | type. For this SMM specific instance of the Memory Allocation Library, \r | |
10 | EfiRuntimeServicesData is used as the default memory type for all allocations.\r | |
11 | In addition, allocation for the Reserved memory types are not supported and \r | |
12 | will always return NULL.\r | |
