It's hard to understand the "secret decisions" about physical platform
firmware. I'm working with a new NUC now, and this one does provide a
functional SerialIo protocol implementation out of the box (with the
"AMI Serial I/O Driver" actually doing its job, unlike in the previous
NUC). However, TerminalDxe is *still* not included in the platform
firmware. Unfathomable. (Well, "TerminalSrc", aka "AMI Terminal Driver"
is included, but like on the earlier NUC, it seems to be doing nothing;
it doesn't bind SerialIo.)
