Detailed Description

Internal ARCH Specific file of MM memory check library.

MM memory check library implementation. This library consumes MM_ACCESS_PROTOCOL to get MMRAM information. In order to use this library instance, the platform should produce all MMRAM range via MM_ACCESS_PROTOCOL, including the range for firmware (like MM Core and MM driver) and/or specific dedicated hardware.
