4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Definition of GUIDed HOB for reserving SMRAM regions.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This file defines:
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * the GUID used to identify the GUID HOB for reserving SMRAM regions.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * the data structure of SMRAM descriptor to describe SMRAM candidate regions
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * values of state of SMRAM candidate regions
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * the GUID specific data structure of HOB for reserving SMRAM regions.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This GUIDed HOB can be used to convey the existence of the T-SEG reservation and H-SEG usage

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync* Inconsistent with specification here:
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync* EFI_HOB_SMRAM_DESCRIPTOR_BLOCK has been changed to EFI_SMRAM_HOB_DESCRIPTOR_BLOCK.
