One of the debugging/logging features for an IPC4 based firmware is the use of the debug window to deliver log messages to host via the shared SRAM. The initial implementation of the mtrace supports only TGL/MTL style of logging, but can be extended to support other types, like APL, SKL, CNL, etc. The window is split into 16 'slots' where the first slot contains the descriptors for the remaining 15 slots. Each DSP core logs to a separate slot and the slot allocation is not fixed, we can not assume that the first slot is always used by core0 for example. The firmware sends LOG_BUFFER_STATUS message when new log batch is available from one of the cores (after it updated the write_ptr in the given slot). Host should update the read_ptr in the same slot when it has taken out log data. The patch also updates the sof_ipc4_fw_data struct with parameters needed for the mtrace to be enabled and used safely.
