Author: ranma Date: Sat Nov 27 10:40:16 2010 New Revision: 6127 URL: https://tracker.coreboot.org/trac/coreboot/changeset/6127
Log: After finding the missing bit poweroff works now. I cleaned up the patch and moved most of the dsdt.dsl and acpi_tables.c into the southbrige/northbridge directory. Updated patch should fix abuild error and incorporates suggestions on irc by uwe (thanks for the comments). Thanks to Idwer Vollering <[email protected]> for the original patch.
