Subject: [Q] "console=" command line ignored?

Hi

I cannot seem to force selection of a serial console by specifying
"console=ttySC0..." on the command line with modern (yesterday's "next")
kernels. The kernel insists on

console [tty0] enabled

The reason might also well be, that the respective "sh-sci" driver is
only registered later. I'll try to look at this in more detail - since
when this is broken and how the registration order looked before. This is
just a first heads-up in case someone has a solution immediately at hand.

Thanks
Guennadi
