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.
