This change adds dynamic initialization of gHobList in GetHobList() to handle cases where library constructors are executed before DxeHobListLibConstructor. Issue: On ARM platforms using ArmMmuBaseLib, the ArmMmuBaseLibConstructor calls GetFirstGuidHob() before xeHobListLibConstructor has initialized gHobList, causing an ASSERT. Root Cause: ArmMmuBaseLib's constructor uses HobLib functions, but UefiPayloadPkg's DxeHobLib assumes gHobList is already initialized by DxeHobListLib's constructor. Solution: Add the same lazy initialization pattern already used in MdePkg/Library/DxeHobLib, which dynamically retrieves the HOB list from the System Configuration Table if gHobList is NULL. This change: - Aligns behavior with MdePkg/Library/DxeHobLib - Has no impact on existing functionality - Improves robustness for ARM platforms Signed-off-by: Jared Pan <jared.pan@dell.com> |
