USB Host Controller Problem

Hi,

I have a custom PowerPC baord based on IBM 405 core with "No PCI".

I have my USB Host controller (OHCI) based with HC registers from
0xef601200.

When I access these address locations, I am getting kernel panic with
machine check interuupt.

Is there any special setting to enable IO address range.

Any help or suggestion will be very helpful...

Thank you,
Regards,
Nageswari
