## Overview

IIO Configuration Update DXE Driver for the LightningRidgeEXECB1 platform.
Registers up to 4 IIO (Integrated IO) configuration protocol instances through
the UBA framework, one per CPU socket. Each instance provides a 1292-byte
(0x50C) IIO configuration table with 21 entries of 12 bytes controlling PCIe
root port and lane partitioning on the Purley platform.

## Key Functions

- **IioCfgUpdateEntry** — entry point, locates UBA board-type protocol and registers all socket tables
- **RegisterSocketConfig** — registers IIO config data for a specific socket index
- **GetIioConfigData** — returns the platform-specific IIO table for a socket

## Protocols / Dependencies

- UBA Board-Type Protocol (board ID 0x0D60)
- IIO CFG Update Protocol (4 instances, one per socket)

## Platform

HR650X Purley (LightningRidgeEXECB1)
