You know, you don't have to mess around with this LCP stuff to get tboot working. I'd recommend ignoring this stuff when you're getting tboot working for the first time. Don't define any NV space. tboot will work fine without them. You'll see some error messages in the log, but they are harmless.
It's too late for you Charles, but for future reference, getting tboot working without defining NV space is much simpler.
