IMHO for board bring up, the very first thing a bootloader should do is
some pin toggling! (ideally there is a LED connected to a pin...) to see if
the board at least comes out of reset and starts at our code.
And then to put out a counter, every time some initialization was finished until
a console is initialized.

I guess most of you came in contact with the Port 0x80 and beep POST codes:

This would help all those without hardware debuggers connected to their board.
