+ * The GPIO control is not well documented in AGESA, but is in the BKDG
+ *
+ * Eg. FANIN1/GPIO57 on datasheet means power-on default (Function0) is to route
+ * from this ball to hardware monitor as FAN1 tacho input. Selecting Function1
+ * routes this to the GPIO block instead. Seems ACPI GPIOs and related GEVENTs
+ * are mostly in Function1, sometimes Function2.
+ *
+ * Note that the GpioOut bit does not mean that the GPIO is an output. That bit
+ * actually controls the output value, so GpioOut means "default to set".
+ * PullUpB is an inverted logic, so setting this bit means we're actually
+ * disabling the internal pull-up. The PullDown bit is NOT inverted logic.
+ * The output driver can be disabled with the GpioOutEnB bit, which is again,
+ * inverted logic. To make the list more readable, we define a few local macros
+ * to state what we mean.
