Where is initial console initialized ?

[Daniel Schnell]

Hi,

Well if one does it right, then things work as expected.

I simply chose the wrong Kernel configuration, the correct console driver has not been compiled in.

Now it works as expected.



Sorry for the noise.

Daniel Schnell.

the dump with:

         reg = <8>;

in most of nodes, which looks just wrong.
