- This file declares the SMM SMRAM Access abstraction protocol, which is used to control
- the visibility of the SMRAM on the platform. The expectation is
- that the north bridge or memory controller would publish this protocol.
- For example, the Memory Controller Hub (MCH) has the hardware provision for this
- type of control. Because of the protected, distinguished class of memory for IA-32
- systems, the expectation is that this protocol would be supported only on IA-32 systems.
