Overview

USB Overcurrent mapping driver for the LightningRidge EX EC B4 platform. Installs a USB OC configuration protocol with port-to-overcurrent-pin mappings selected at runtime by reading CMOS index 0x4B (board revision strap). Supports three pre-compiled mapping tables for different board revisions.

Key Functions

• _ModuleEntryPoint — Initializes globals, gets HOB list, reads board revision, installs USB OC protocol
• GetUsbOcConfigTables — Returns the USB OC mapping table for the detected board revision
• DebugPrintEx — Conditional debug output with CMOS-based platform type filtering

Protocols / Dependencies

• UBA USB OC Protocol
• EFI HOB List
• CMOS register 0x4B (board revision selection)

Platform

LightningRidge EX EC B4 (three board revision tables: Default, Alt/B2 stepping, Extended)
