Hi all,

I have an issue on tty terminal. I setup PL011 serial console as the
tty terminal on HiKey platform. When it's built in debug mode, arrow
key works well. When it's built in release mode, arrow key can't work.

For example, DOWN key is gotten in terminal with "~[B" value in debug
build. DOWN key is gotten in terminal with "~" value in release build.
These values are fetched by GetOneKeyFromSerial().

But I can't find any difference on PL011 serial driver between debug
and release mode.

Do you have any idea on this?

Best Regards
Haojian
