Help on OHCI USB host present in SM501 chip

[robinpv]

Hi ,
I am using MPC5200 based board and i have SM501 Mobile Multimedia 
companion chip on the PCI bus.
I am writing OHCI USB host present on the SM501 chip. I wanted to know 
if driver already exists.
I searched in linux ppc,  i could find the driver for the VGA( 
controller present in SM501) but not USB.
Currently i am referring to ohci-sa1111.c as reference.

Thanks in advance
Robin
