Hi,
The series adds the basic IPC4 message handling code, implementing the ipc callbacks. Due to the difference between IPC3 and IPC4 messaging we need to introduce new message container for IPC4, but the SOF internal callbacks and structures can be kept as they were and leaving it for the IPC specific code to handle the differences.
The series provides the foundation for both lowe level (sound/soc/sof/intel) and high level IPC4 implementation (topologies, firmware loading, control handling, etc).
