- CpuIo.c
-
-Abstract:
-
- This is the code that publishes the CPU I/O Protocol.
- The intent herein is to have a single I/O service that can load
- as early as possible, extend into runtime, and be layered upon by
- the implementations of architectural protocols and the PCI Root
- Bridge I/O Protocol.
