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