Author: sduplichan Date: Tue Oct 19 06:36:42 2010 New Revision: 5967 URL: https://tracker.coreboot.org/trac/coreboot/changeset/5967
Log: To reduce boot time, remove the double startup IPI and 10 ms delay from lapic_cpu_init.c. The change is currently restricted to recent model AMD processors, though it could be applied to others after successful testing.
