Overview

UBA (Unified Board Architecture) OpromUpdate DXE driver for the LightningRidge (C621/C622) EXEC B2 board. Registers 5 PCIe slot/port configuration callbacks with the UBA Config Protocol so that the central OpromUpdate DXE driver can query board-specific slot population and OpROM configuration data.

Key Functions

IsFunctionInPopulatedSlot -- Validates PCIe root port slot presence via config space
GetBoardInfo -- Returns board identification data
GetSlotConfig1 / GetSlotConfig2 -- Register PCIe slot config tables
SetPcieSlotNumber -- Slot number setter callback
_ModuleEntryPoint -- DXE entry point; caches UEFI globals, registers PBDS table

Dependencies

EFI_PCI_IO_PROTOCOL, UBA_DEBUG_PROTOCOL, UBA_CONFIG_PROTOCOL, UBA OpromUpdate Board GUID

Platform

HR650X Purley (Intel C621/C622, Lewisburg PCH)
