How about having a generic r/w access to target memory via debugfs?
Userspace would deal with the extraction of the cal data. Or do you
want to make it easier for the user to provide the cal data without
any extra tools (and that sending entire unprocessed target memory
dump may introduce some privacy concerns)?
