* [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.

Changes

  • 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. <trac>12662</trac>.
  • 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. <trac>12660</trac>.
