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.
