to assert validity of trace logs. Value used in sof-logger.

@ktrzcinx when you say 'value is used by sof-logger', did you mean that the value would be exposed in a debugfs value read by sof-logger?

[ktrzcinx]

@plbossart sof_ipc_fw_version is part of fw_ready message, already saved in debugfs and already used by sof-logger for compatibility check

[ktrzcinx]

FW part has been merged already, so this PR also should keep going.

@ktrzcinx I need more coffee but do we actually need this from the firmware, can't we get it from the extended manifest?

[ktrzcinx]

@plbossart actually not, because only fw_ready message is accessible from sof-logger point of view. Logger is default reader of this information, here it's only added to keep data structures aligned.

ok, thanks for the clarification

[plbossart]

@kv2019i can you take a look (ABI, etc)? Thanks!

@plbossart Ack, I'm having some doubts on this -- kernel doesn't use this field, so why add it to the header. But given we don't annotate the changes to FW headers (I have an AR to fix that), keeping them in sync in other ways is problematic as well. Oh well, let's put this in.
