/*
* CpuCP Primary Queue Packets
*
* During normal operation , the host ' s kernel driver needs to send various
* messages to CpuCP , usually either to SET some value into a H / W periphery or
* to GET the current value of some H / W periphery . For example , SET the
* frequency of MME / TPC and GET the value of the thermal sensor .
*
* These messages can be initiated either by the User application or by the
* host ' s driver itself , e . g . power management code . In either case , the
* communication from the host ' s driver to CpuCP will * always * be in
* synchronous mode , meaning that the host will send a single message and poll
* until the message was acknowledged and the results are ready ( if results are
* needed ) .
*
* This means that only a single message can be sent at a time and the host ' s
* driver must wait for its result before sending the next message . Having said
* that , because these are control messages which are sent in a relatively low
* frequency , this limitation seems acceptable . It ' s important to note that
* in case of multiple devices , messages to different devices * can * be sent
* at the same time .
*
* The message , inputs / outputs ( if relevant ) and fence object will be located
* on the device DDR at an address that will be determined by the host ' s driver .
* During device initialization phase , the host will pass to CpuCP that address .
* Most of the message types will contain inputs / outputs inside the message
* itself . The common part of each message will contain the opcode of the
* message ( its type ) and a field representing a fence object .
*
* When the host ' s driver wishes to send a message to CPU CP , it will write the
* message contents to the device DDR , clear the fence object and then write to
* the PSOC_ARC1_AUX_SW_INTR , to issue interrupt 121 to ARC Management CPU .
*
* Upon receiving the interrupt ( # 121 ) , CpuCP will read the message from the
* DDR . In case the message is a SET operation , CpuCP will first perform the
* operation and then write to the fence object on the device DDR . In case the
* message is a GET operation , CpuCP will first fill the results section on the
* device DDR and then write to the fence object . If an error occurred , CpuCP
* will fill the rc field with the right error code .
*
* In the meantime , the host ' s driver will poll on the fence object . Once the
* host sees that the fence object is signaled , it will read the results from
* the device DDR ( if relevant ) and resume the code execution in the host ' s
* driver .
*
* To use QMAN packets , the opcode must be the QMAN opcode , shifted by 8
* so the value being put by the host ' s driver matches the value read by CpuCP
*
* Non - QMAN packets should be limited to values 1 through ( 2 ^ 8 - 1 )
*
