/*
 * 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)
 *

 *       NIC port and the speed.
 *
 * CPUCP_PACKET_MSI_INFO_SET -
 *       set the index number for each supported msi type going from
 *       host to device
 *
 * CPUCP_PACKET_NIC_XPCS91_REGS_GET -
 *       Fetch the un/correctable counters values from the NIC MAC.
 *
 * CPUCP_PACKET_NIC_STAT_REGS_GET -
 *       Fetch various NIC MAC counters from the NIC STAT.
 *
 * CPUCP_PACKET_NIC_STAT_REGS_CLR -
 *       Clear the various NIC MAC counters in the NIC STAT.
 *
 * CPUCP_PACKET_NIC_STAT_REGS_ALL_GET -
 *       Fetch all NIC MAC counters from the NIC STAT.
 *
 * CPUCP_PACKET_IS_IDLE_CHECK -
 *       Check if the device is IDLE in regard to the DMA/compute engines
 *       and QMANs. The f/w will return a bitmask where each bit represents
 *       a different engine or QMAN according to enum cpucp_idle_mask.
 *       The bit will be 1 if the engine is NOT idle.
 *
 * CPUCP_PACKET_HBM_REPLACED_ROWS_INFO_GET -
 *       Fetch all HBM replaced-rows and prending to be replaced rows data.
 *
 * CPUCP_PACKET_HBM_PENDING_ROWS_STATUS -

 *
 * CPUCP_PACKET_ENGINE_CORE_ASID_SET -
 *       Packet to perform engine core ASID configuration
 *
 * CPUCP_PACKET_SEC_ATTEST_GET -
 *       Get the attestaion data that is collected during various stages of the
 *       boot sequence. the attestation data is also hashed with some unique
 *       number (nonce) provided by the host to prevent replay attacks.
 *       public key and certificate also provided as part of the FW response.
 *
 * CPUCP_PACKET_MONITOR_DUMP_GET -
 *       Get monitors registers dump from the CpuCP kernel.
 *       The CPU will put the registers dump in the a buffer allocated by the driver
 *       which address is passed via the CpuCp packet. In addition, the host's driver
 *       passes the max size it allows the CpuCP to write to the structure, to prevent
 *       data corruption in case of mismatched driver/FW versions.
 *       Relevant only to Gaudi.
 *
 * CPUCP_PACKET_GENERIC_PASSTHROUGH -
 *      Generic opcode for all firmware info that is only passed to host
 *      through the LKD, without getting parsed there.
 *
 * CPUCP_PACKET_ACTIVE_STATUS_SET -
 *       LKD sends FW indication whether device is free or in use, this indication is reported
 *       also to the BMC.
