weighing in

[steven james]

Greetings,

I just looked at that code. I see what you mean.

A question there, we are still going to want early serial output. It's
ugly, but could special cases like that go into preram init? That does
look like a step back to what we have now, but it may be hard to help in
corner cases, and would allow for a neat and clean init for most chipsets.

The question is, it thats's done, would the exception become the rule?

G'day,
sjames
