Yes, this is a chioce, or we can make TERMIOS enabled forcely, but
will cause a extra 1KB overhead for all target.
That 1Kb number seems large to me. Most of that is in the lower-half,
UART driver, right? If so then the size would vary dramatically from
chip-to-chip.
As a percentage growth, I suppose even 1Kb is not so large. Probably
less then 2%
