/** @file
|
|
This file defines:
|
|
* the capsule vendor GUID for capsule variables and the HOB.
|
|
* the capsule variable name.
|
|
* the capsule GUID HOB data structure.
|
|
The capsule HOB and variable can be used to store the capsule image start address and length.
|
|
They are used by EDKII implementation of capsule update across a system reset.
|
|
|
|
@par Note: EDKII implementation of capsule updating has discarded this capsule GUID HOB data
|
|
structure and used one UEFI Capsule HOB (defined in PI Specification 1.2) instead.
