Hi,

The console driver provides early console which should initialize
without any transport. I have not tested it actually works but the code
seems to be there to support this use case.

What does it do if it hasn't got any transport yet ?

Just eat the bits or buffer everything, until it gets a transportport
and sends out later ?

Why would it need the transport?

It's not like the data goes through an actual PCI bus, it is only used
for discovering and configuring the device, right?

Then if you do ad-hoc configuration of the device you do not need the
trasport at all.

Thanks
