/*
 * 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)
 *
 * Detailed description:
