[Stefan Reinauer]

* Tobias Diedrich <ranma+coreboot at tdiedrich.de> [101122 15:36]:
> With low serial console loglevels a pcie graphics card is not
> initialized properly because the pcie link takes some time to come
> up.
> 
> I set the timeout rather arbitrary to 100ms, this is what a BIOS_ERR
> and higher only boot looks like on my system (with pcie printks set
> to BIOS_ERR so they show up):
