Revision ea8d006b91ac58ec5a0862d09e0b629db399517f authored by Stefan Richter on 01 March 2008, 01:42:56 UTC, committed by Stefan Richter on 13 March 2008, 23:56:58 UTC 
firewire: fw-ohci: PPC PMac platform code
 
Copied from ohci1394.c.  This code is necessary to prevent machine check
exceptions when reloading or resuming the driver.

Tested on a 1st generation PowerBook G4 Titanium, which also needs the
pci_probe() hunk.

I was able to reproduce the system exception on resume with a 3rd-gen
Titanium PowerBook G4 667, and this patch does let the system resume
successfully now.

Not quite clear if there was possibly an updated version coming using
pci_enable_device() instead of the pair of pmac_call_feature() calls,
but either way, this is a definite must-have, at least for older ppc
macs -- my Aluminum PowerBook G4/1.67 suspends and resumes without this
patch just fine.
