/*
* 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)
*
