OpromUpdateDxeNeonCityFPGA

Overview

OpromUpdateDxeNeonCityFPGA provides Option ROM (OpROM) update configuration for the NeonCityFPGA platform via the UBA protocol. It registers callback functions that define PCIe slot-to-adapter mappings, enabling the platform to correctly configure option ROMs for installed PCIe devices. The driver scans for enabled PCIe slots via the PCI Root Bridge I/O Protocol and publishes OpROM configuration data through UBA callbacks.

Key Functions

• _ModuleEntryPoint -- Entry point; caches system table pointers, locates HOB list, finds UBA protocol, registers OpROM configuration
• GetHobList -- Scans SystemTable->ConfigurationTable[] for EFI_HOB_LIST_GUID
• GetDebugProtocol -- Resolves and caches DebugLib protocol interface
• DebugPrint -- Debug output via DebugLib protocol
• DebugAssert -- Assertion handler via DebugLib protocol
• IsGuidEqual -- Two-64-bit GUID comparison
• GetPcieSlotConfigProtocol0 -- Callback that provides PCIe slot configuration protocol
• ReadUnaligned64 -- Unaligned 64-bit memory read with NULL check
