Here I disagree. The concept of "pre-console panic" as used here is
broken.
We should _always_ initialize this "single fixed UART" as debug
console as early as possible. Period.
If we have a "pre-console panic" then, we cannot do anything about it,
because if "as early as possible" is not sufficient, then it cannot be
helped - obviously we cannot initialize the UART before that.
And any panic after that is just anormal thing that can be printed on
the debug console port. No need for any special handling.
Best regards,
Wolfgang Denk
