Once that's working, we can convert individual PPC platforms over, removing the routines from the ppc_md and creating a generic RTC driver instead. PA Electra is already like that -- because it wasn't a regression there to have broken NTP sync. But the others need to wait. Eventually, we ought to be able to drop the RTC functions from the ppc_md -- and presumably the equivalent for other architectures too. -- David Woodhouse Open Source Technology Centre David.Woodhouse@intel.com Intel Corporation
