| 444bf90d | 2 | Definition of GUIDed HOB for reserving SMRAM regions.\r |
| 3 | \r | |
| 4 | This file defines:\r | |
| 5 | * the GUID used to identify the GUID HOB for reserving SMRAM regions.\r | |
| 6 | * the data structure of SMRAM descriptor to describe SMRAM candidate regions\r | |
| 7 | * values of state of SMRAM candidate regions\r | |
| 8 | * the GUID specific data structure of HOB for reserving SMRAM regions.\r | |
| 9 | This GUIDed HOB can be used to convey the existence of the T-SEG reservation and H-SEG usage\r | |
