commit 6e669594a15db67c9ee8e2632d05540a8e3bf9e6 Author: Paul Menzel paulepanter@users.sourceforge.net Date: Fri Jun 14 23:42:45 2013 +0200
cpu/x86/lapic/lapic_cpu_init.c: Remove double startup IPI for AMD AGESA processors
Many CPU families no longer the double startup IPI. Add CPU_AMD_AGESA as one indicator that it is not needed, as all AMD processors using AGESA – currently Family 10h to 15h – should not need it.
Successfully tested on ASRock E350M1 with a Family 14h processor.
