Log: Fix power_on_after_fail handling on AMD SB600 Bit 0 of pm reg#74 have to be set turn on system after power resumes. See '42661_sb600_rrg_nda_3.02.pdf' (or '46155_sb600_rrg_pub_3.03.pdf') for details, look for 'PwrFailShadow'. [Patrick: I didn't include the get_options reorganization as get_option doesn't overwrite "on" if power_on_after_fail isn't found in CMOS. Style changes were also left out.] Signed-off-by: Josef Kellermann <[email protected]> Acked-by: Patrick Georgi <[email protected]> Modified: trunk/src/southbridge/amd/sb600/sm.c Modified: trunk/src/southbridge/amd/sb600/sm.c ============================================================================== --- trunk/src/southbridge/amd/sb600/sm.c Thu Mar 17 13:20:04 2011 (r6450) +++ trunk/src/southbridge/amd/sb600/sm.c Thu Mar 17 13:34:15 2011 (r6451) @@ -94,7 +94,7 @@ byte = pm_ioread(0x74); byte &= ~0x03; if (on) { - byte |= 2; + byte |= 1 << 0; } byte |= 1 << 2; pm_iowrite(0x74, byte); -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
