+ * GSC proxy:

+ * and back. i915 must manually start the proxy flow after the GSC is loaded to
+ * signal to GSC that we're ready to handle its messages and allow it to query
+ * its init data from CSME; GSC will then trigger an HECI2 interrupt if it needs
+ * to send messages to CSME again.
+ * The proxy flow is as follow:
+ * 1 - i915 submits a request to GSC asking for the message to CSME
+ * 2 - GSC replies with the proxy header + payload for CSME
+ * 3 - i915 sends the reply from GSC as-is to CSME via the mei proxy component
+ * 4 - CSME replies with the proxy header + payload for GSC
+ * 5 - i915 submits a request to GSC with the reply from CSME
+ * 6 - GSC replies either with a new header + payload (same as step 2, so we
