 * This file does a bunch of tests to make sure that we correctly handle cases
 * where we're asked to decode the following types of addresses:
 *
 *   - Legacy Reserved Addresses
 *   - Between TOLM, TOHM
 *   - Above TOHM

/*
 * This IMC represents a basic case where we have a single 8 GiB dual rank DIMM.
 * We have system memory in the lower 2 GiB and then the remaining 6 GiB starts
 * at the bottom of high memory (4 GiB).
