If you run bootmenu in U-Boot it will print following output:

Last entry is being overwritten by "Hit any key to stop autoboot" and then every one second is new text appended after this last entry with updated countdown. This is broken... I run git bisect and the result is:

Simon, could you look at this issue? It can be simple reproduced just by calling "bootmenu" command.
Not only autoboot countdown and last boot entry is broken but also keys UP and DOWN and broken on _terminal_. When I do not press any key on terminal for 3 seconds then pressing DOWN quits bootmenu. Git bisect found same above commit. Maybe added "case '\e':" in above commit into /* ^C was pressed */ branch cause it?
Hm... what does "+#define ansi 0" in that commit means? It looks like a hack for some unfinished stuff. That commit is incomplete.
Hmm I will take a look either tomorrow or in a few weeks.
Regards, Simon
