UsbOcUpdateDxeNeonCityFPGA

Overview

UEFI DXE driver for USB over-current (OC) protection configuration on the
NeonCityFPGA platform. Registers port-to-OC-pin mappings through the UBA
framework, including front panel (16 ports) and rear panel/backplane (20 ports)
USB OC mappings. Debug output is controlled via CMOS register 0x4B at RTC
ports 0x70/0x71.

Key Functions

• _ModuleEntryPoint — initializes globals, locates HOB list and UBA board-type protocol, registers USB OC config
• GetHobList — scans SystemTable->ConfigurationTable for EFI_HOB_LIST_GUID
• DebugPrint — resolves DebugLib protocol and calls output function
• DebugAssert — calls DebugLib assertion handler
• ReadUnaligned64 — reads 64-bit value from potentially unaligned memory

Protocols / Dependencies

• UBA Board-Type Protocol
• USB OC Configuration Protocol
• DebugLib Protocol
