Detailed Description

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.

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.

Name of capsule variable.

#define EFI_CAPSULE_VENDOR_GUID   { 0x711C703F, 0xC285, 0x4B10, { 0xA3, 0xB0, 0x36, 0xEC, 0xBD, 0x3C, 0x8B, 0xE2 } }

This guid is used as a variable GUID for the capsule variable if the capsule pointer is passed through reset via a variable.

This guid is also used as a hob GUID for the capsule data when the capsule pointer is passed from PEI phase to DXE phase.
