Is it possible to put OpenFirmware on an SD card and use it to boot off e.g. a USB-attached mass storage device or using TFTP over a LAN? -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues]

[commit] r3651 - cpu/x86/pc/olpc/via dev

April 28, 2013

Author: quozl Date: Mon Apr 29 08:02:14 2013 New Revision: 3651 URL: http://tracker.coreboot.org/trac/openfirmware/changeset/3651 Log: 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.
