Initialization code/data memory mapping system

An Information Handling System (IHS), comprising:

• a processing system that is configured to:
• access, via first Memory Mapped Input/Output (MMIO) read operations, initialization code stored in at least one memory device that is mapped to an initialization memory space in order to provide an initialization engine;
• copy, using the initialization engine, the initialization code from the at least one memory device to a main memory system;
• access the initialization code stored in the main memory system in order to provide the initialization engine;
• map, using the initialization engine provided via the initialization code stored in the main memory system, initialization data stored in the at least one memory device to the initialization memory space, wherein the mapping the initialization data stored in the at least one memory device to the initialization memory space hides the initialization code in a runtime environment that is provided following completion of initialization operations by unmapping the initialization code stored in the at least one memory device from the initialization memory space;
• and
• access, via second MMIO read operations, the initialization data stored in the at least one memory device that is mapped to the initialization memory space for use by the initialization engine.

A method for mapping initialization code memory and initialization data memory, comprising:

• accessing, by a processing system via first Memory Mapped Input/Output (MMIO) read operations, initialization code stored in at least one memory device that is mapped to an initialization memory space in order to provide an initialization engine;
• copying, by the processing system using the initialization engine, the initialization code from the at least one memory device to a main memory system;
• accessing, by the processing system, the initialization code stored in the main memory system in order to provide the initialization engine;
• mapping, by the processing system using the initialization engine provided via the initialization code stored in the main memory system, the initialization data stored in the at least one memory device to the initialization memory space, wherein the mapping the initialization data stored in the at least one memory device to the initialization memory space hides the initialization code in a runtime environment that is provided following completion of initialization operations by unmapping the initialization code stored in the at least one memory device from the initialization memory space;
• and
• accessing, by the processing system via second MMIO read operations, the initialization data stored in the at least one memory device that is mapped to the initialization memory space for use by the initialization engine.
