Key Functions

• UefiBootServicesTableLibConstructor -- saves ImageHandle, gST, gBS, gRT
• DxeLnvPurleyDriverInit -- Lenovo-specific DXE initialization
• GetPlatformType -- reads CMOS 0x4B and MMIO to determine platform variant
• NotifyFunction -- generic event notification handler

Protocols/Dependencies
