60 * reference updated on the completion of writes. Each tester reads
61 * and writes a specific byte in a cache line, as determined by its
62 * unique id. Thus, all requests issued by the MemTest instance are a
63 * single byte and a specific address is only ever touched by a single
64 * tester.
65 *
66 * In addition to verifying the data, the tester also has timeouts for
67 * both requests and responses, thus checking that the memory-system
68 * is making progress.
