Author: quozl Date: Thu Mar 28 00:57:22 2013 New Revision: 3631 URL: http://tracker.coreboot.org/trac/openfirmware/changeset/3631 Log: OLPC - avoid use of RTC undefined data, by detecting power loss and clearing the RTC count. XO-1 and XO-1.5 (ds1385): clear all the RTC count registers, not only the date. XO-1.75 and XO-4 (ds1338): force the century to 20 like on previous models, check and clear the oscillator stop flag, clear all the RTC count registers, separate the clearing of RTC SRAM from the clearing of RTC count, and fix a regression in r3608 where the wrong register offsets were used.
