From: Venkatesh Yadav Abbarapu <venkatesh.abbarapu at amd.com>

Crashes are occurring due to the number of reserved memory regions
exceeding the current maximum limit of 16. It is recommended to
increase the supported number of memory regions to 64, as newer
platforms may utilize more reserved regions.
