+ * SGS M48-T59Y TOD/NVRAM Driver
+ *
+ * The SGS M48 an 8K NVRAM starting at offset M48_BASE_ADDR and
+ * continuing for 8176 bytes. After that starts the Time-Of-Day (TOD)
+ * registers which are used to set/get the internal date/time functions.
+ *
+ * This module implements Y2K compliance by taking full year numbers
+ * and translating back and forth from the TOD 2-digit year.
+ *
+ * NOTE: for proper interaction with an operating system, the TOD should
+ * be used to store Universal Coordinated Time (GMT) and timezone
+ * conversions should be used.
