[LinuxBIOS] Enabling USB 2.0

[Anil B G]

Hi,
  I am trying to enable USB on a board similar to Tyan s2892 (CK804)
chipset?
Is there anything that else that needs to be done separately other than
setting the irqs et al correctly? Specifically do we need to write some sort
of a driver to enable the USB host controller.

Thanks
Anil
