/** @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. | |
