A number of arches have moved over to using the generic read_persisitent_clock or update_persisitent_clock implementations instead of manipulating xtime themselves.
This patchset tries to convert the remaining arches over and will allow for further generic timekeeping cleanups.
There is some issues where the RTC/persistent clock is behind a bus that requires irqs to access. This patch is not trying to handle those cases, and instead is just using whatever method was used at time_init to initialize xtime.
I sent this set out back in December to only a bit of discussion (many thanks to the testers who provided feedback!). But I wanted to send it out again to try to get this moving again.
Any feedback or comments would be appreciated.
thanks -john
