This is a special GUID extension Hob to describe SMRAM memory regions.
|
||
|
|
|
||
|
|
This file defines:
|
||
|
|
* the GUID used to identify the GUID HOB for reserving SMRAM regions.
|
||
|
|
* the data structure of SMRAM descriptor to describe SMRAM candidate regions
|
||
|
|
* values of state of SMRAM candidate regions
|
||
|
|
* the GUID specific data structure of HOB for reserving SMRAM regions.
