High Precision Timer on JS20

Hi,

I'm now trying to use the High Precision Timer (HPET) of the 8111
Hypertransport IO hub. This function is part of the LPC sub-device which
is supposed to be probed as a pci sub-device (device B, function 0 in
the IO Hub doc.).

But it seems that the only sub-device listed in the device tree and
detected through the pci scan is the IDE controller which is the
function 1 of this part of the IO hub.

Even trying to reach the function 0 (and the other available functions)
through pci_config_read call is failing (returning 0xffffffff).

Did I miss something ? Is there a control of the pci function number in
the related RTAS call ?

Regards.
