+ * ACPI does not define a mechanism for AML methods to call native firmware
+ * interfaces such as PAL or SAL.  This OpRegion handler adds such a mechanism.
+ * After the handler is installed, an AML method can call native firmware by
+ * storing the arguments and firmware entry point to specific offsets in the
+ * OpRegion.  When AML reads the "return value" offset from the OpRegion, this
+ * handler loads up the arguments, makes the firmware call, and returns the
+ * result.
