Memory Mapped Register Space
All System Memory control functions have been consolidated into a new memory mapped address region
within Device 0 Function 0. This space will be accessed using a new Base Address Register (BAR)
located at Dev 0 Func 0 (Offset 14h). By default this BAR will be invisible (i.e., Read-Only zeros).
Note: All accesses to these Memory Mapped Registers must be made as a single DWORD (4 bytes) or less.
Access must be aligned on a natural boundary.
The high-level breakout of these memory-mapped registers is as follows.
