* [http://tracker.coreboot.org/trac/openfirmware/changeset/3651 3651] OLPC XO-1 - suppress the RTC amnesia check introduced in r3649, because the VRT bit works fine, and the century value at 0x1a is occasionally cleared by a power cycle. This clearing is ingored by ds1385r.fth get-time, which forces the returned century to 0x20. Curiously, the century value at 0x32 (as set by MSR 5140.0057) is not used in ds1385r.fth, and keeps what Linux set it to.
* [http://tracker.coreboot.org/trac/openfirmware/changeset/3650 3650] OLPC XO-1 XO-1.5 - maintain the NFS RPC XID in CMOS RAM, so that scripted NFS actions do not fail silently. Different location used for XO-1 because the default location is reset by a power cycle. #12662.
* [http://tracker.coreboot.org/trac/openfirmware/changeset/3649 3649] OLPC XO-1.5 - the Valid RAM and Time (VRT) bit in RTC register 0xd can't be trusted on the XO-1.5, so use other means to detect loss of data. This works in most cases, but there is still the possibility of data corruption when the battery is missing or discharged. #12600.
