Having read the whole series now, my conclusion is that we don't want
to do that. The way AMD is storing this string in a type 40 record is
absolutely not how these records are supposed to be used. So having
generic code to store and retrieve strings from type 40 records is
neither needed nor desirable.

This is a hack from AMD, the best way to deal with it is with the
minimum amount of code in the kernel and smallest memory footprint.
Simply catch the string when you see it, log it, and be done with it.
