# IioCfgUpdateDxeLightningRidgeEXECB4

**Index**: 0038 | **Size**: 3776 bytes | **Arch**: x64 | **Phase**: DXE

## Overview
IIO Configuration Update DXE driver for the LightningRidge EX EC B4 platform. Registers platform-specific IIO configuration data (bifurcation mapping, PCIe slot config, SMBUS config) with the UBA framework via four GUID-keyed protocol instances.

## Key Functions
- _ModuleEntryPoint — Caches globals, retrieves HOB list, prints banner, registers IIO platform data
- RegisterIioConfigPlatformData — Locates UBA IIO protocol and dispatches config header to four IIO stacks
- DebugLogPrint — Conditional debug output via CMOS platform type detection

## Protocols / Dependencies
- UBA IIO Configuration Protocol (4 GUIDs)
- UBA Debug Protocol
- HOB List

## Platform
LightningRidge EX EC B4 (3424 bytes total config, 60 bifurcation entries, 1292 slot configs, 3120 SMBUS configs)
