+ * There are 2 versions of production Sequoia & Rainier platforms.
+ * The primary difference is the reference clock. Those with
+ * 33333333 reference clocks will also have 667MHz rated
+ * processors. Not enough differences to have unique clock
+ * settings.
+ *
+ * NOR and NAND boot options change bytes 6, 7, 8, 9, 11. The
+ * values are independent of the rest of the clock settings.
+ *
+ * All Sequoias & Rainiers select from two possible EEPROMs in Boot
+ * Config F. One for 33MHz PCI, one for 66MHz PCI. The following
+ * values are for the 33MHz PCI configuration. Byte 5 (0 base) is
+ * the only  value affected for a 66MHz PCI and simply needs a +0x10.
