Overview

UbaInitPei is the PEI entry point for the UBA (Unified Board Architecture) subsystem. It initializes the UBA protocol and locates the platform type information during early PEI. The module provides helper functions for HOB traversal, GUID comparison, debug logging, and PEI service access that are used by the broader UBA initialization framework.

Key Functions

UbaInitEntryPoint -- Main entry point; initializes UBA protocol and platform type detection
UbaGetPlatformType -- Retrieves the platform type identifier
UbaGetProtocol -- Locates UBA protocols from the PEI database
UbaGetHobList / UbaFindHobByType -- HOB list traversal for UBA configuration data
UbaDebugPrint / UbaAssertHandler -- Debug and assertion services
UbaGuidCompare / UbaReadQword -- Utility helpers for GUID comparison and memory access

Dependencies

MdePkg (BaseMemoryLib, BaseLib)
PEI Services (HOB traversal, PPI location)
UBA protocol definitions

Platform

Intel Purley platform, Lenovo HR650X server.
