398  * CpuCP Primary Queue Packets
399  *
400  * During normal operation, the host's kernel driver needs to send various
401  * messages to CpuCP, usually either to SET some value into a H/W periphery or
402  * to GET the current value of some H/W periphery. For example, SET the
403  * frequency of MME/TPC and GET the value of the thermal sensor.
404  *
405  * These messages can be initiated either by the User application or by the
406  * host's driver itself, e.g. power management code. In either case, the
407  * communication from the host's driver to CpuCP will *always* be in
408  * synchronous mode, meaning that the host will send a single message and poll
409  * until the message was acknowledged and the results are ready (if results are
410  * needed).
411  *
412  * This means that only a single message can be sent at a time and the host's
413  * driver must wait for its result before sending the next message. Having said
414  * that, because these are control messages which are sent in a relatively low
415  * frequency, this limitation seems acceptable. It's important to note that
416  * in case of multiple devices, messages to different devices *can* be sent
417  * at the same time.
418  *
419  * The message, inputs/outputs (if relevant) and fence object will be located
420  * on the device DDR at an address that will be determined by the host's driver.
421  * During device initialization phase, the host will pass to CpuCP that address.
422  * Most of the message types will contain inputs/outputs inside the message
423  * itself. The common part of each message will contain the opcode of the
424  * message (its type) and a field representing a fence object.
425  *
426  * When the host's driver wishes to send a message to CPU CP, it will write the
427  * message contents to the device DDR, clear the fence object and then write to
428  * the PSOC_ARC1_AUX_SW_INTR, to issue interrupt 121 to ARC Management CPU.
429  *
430  * Upon receiving the interrupt (#121), CpuCP will read the message from the
431  * DDR. In case the message is a SET operation, CpuCP will first perform the
432  * operation and then write to the fence object on the device DDR. In case the
433  * message is a GET operation, CpuCP will first fill the results section on the
434  * device DDR and then write to the fence object. If an error occurred, CpuCP
435  * will fill the rc field with the right error code.
436  *
437  * In the meantime, the host's driver will poll on the fence object. Once the
438  * host sees that the fence object is signaled, it will read the results from
439  * the device DDR (if relevant) and resume the code execution in the host's
440  * driver.
441  *
442  * To use QMAN packets, the opcode must be the QMAN opcode, shifted by 8
443  * so the value being put by the host's driver matches the value read by CpuCP
444  *
445  * Non-QMAN packets should be limited to values 1 through (2^8 - 1)
446  *
447  * Detailed description:
448  *
449  * CPUCP_PACKET_DISABLE_PCI_ACCESS -
450  *       After receiving this packet the embedded CPU must NOT issue PCI
451  *       transactions (read/write) towards the Host CPU. This also include
452  *       sending MSI-X interrupts.
453  *       This packet is usually sent before the device is moved to D3Hot state.
454  *
455  * CPUCP_PACKET_ENABLE_PCI_ACCESS -
456  *       After receiving this packet the embedded CPU is allowed to issue PCI
457  *       transactions towards the Host CPU, including sending MSI-X interrupts.
458  *       This packet is usually send after the device is moved to D0 state.
459  *
460  * CPUCP_PACKET_TEMPERATURE_GET -
461  *       Fetch the current temperature / Max / Max Hyst / Critical /
462  *       Critical Hyst of a specified thermal sensor. The packet's
463  *       arguments specify the desired sensor and the field to get.
464  *
