+ * command; other device mapping is board-specific.
+ *
+ * When a device receives a command to be passed to a sub-processor, it passes

+ * to remain blissfully unaware of whether the command originated on the next
+ * device up the chain, or was passed through from the AP.
+ *
+ * In the above example, if the AP wants to send command 0x0002 to the PD MCU,
+ * AP sends command 0x4002 to the EC
+ * EC sends command 0x0002 to the PD MCU
+ * EC forwards PD MCU response back to the AP
