/*
- * Pre-RAM driver for the Fintek F71869AD Super I/O chip.
+ * A generic romstage (pre-ram) driver for Fintek variant Super I/O chips.
*
- * Derived from p.34 in vendor data-sheet:
+ * The following is derived directly from the vendor Fintek's data-sheets:
*
- * - default index port : 0x4E
- * - default data port : 0x4F
+ * To toggle between `configuration mode` and `normal operation mode` as to
+ * manipulation the various LDN's in Fintek Super I/O's we are required to pass
+ * magic numbers `passwords keys`.
*
- * - enable configuration : 0x87
- * - disable configuration : 0xAA
+ * FINTEK_ENTRY_KEY := enable configuration : 0x87
+ * FINTEK_EXIT_KEY := disable configuration : 0xAA
+ *
+ * To modify a LDN's configuration register, we use the index port to select
+ * the index of the LDN and then writing to the data port to alter the
+ * parameters. A default index, data port pair is 0x4E, 0x4F respectively, a
+ * user modified pair is 0x2E, 0x2F respectively.
