of an inbound message.
+I/O Request Workflow of Marvell Frey
+--------------------------------------
+
+All queued requests are handled via inbound/outbound list.
+
+To send a request to the controller:
+
+ - Allocate a free request in host DMA coherent memory.
+
+ Requests allocated in host memory must be aligned on 32-bytes
boundary.
+
+ - Fill the request with index of the request in the flag.
+
+ Fill a free inbound list unit with the physical address and the
size of
+ the request.
+
+ Set up the inbound list write pointer with the index of previous
unit,
+ round to 0 if the index reaches the supported count of requests.
+
+ - Post the inbound list writer pointer to IOP.
+
+ - The IOP process the request. When the request is completed, the
flag of
+ the request with or-ed IOPMU_QUEUE_MASK_HOST_BITS will be put into a
+ free outbound list unit and the index of the outbound list unit
will be
+ put into the copy pointer shadow register. An outbound interrupt
will be
+ generated.
+
+ - The host read the outbound list copy pointer shadow register and
compare
+ with previous saved read ponter N. If they are different, the
host will
+ read the (N+1)th outbound list unit.
+
+ The host get the index of the request from the (N+1)th outbound list
+ unit and complete the request.
+
+Non-queued requests (reset communication/reset/flush etc) can be sent
via PCIe
+Function 0 to CPU Message A register. The CPU to PCIe Function 0
Message register
+with the same value indicates the completion of message.
