From 2bdfb48b13ab5c392ef2b1dd9a8bfda6c90b2e18 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Tue, 3 Apr 2012 16:17:11 -0700 Subject: Fixes and Sandybridge support for lapic cpu init - preprocessor macros should not use defined(CONFIG_*) but just CONFIG_* - drop AMD CPU model 14XXX config variable use. Those do not exist. - skip some delays on Sandybridge systems - Count how long we're waiting for each AP to stop - Skip speedstep specific CPU entries Change-Id: I13db384ba4e28acbe7f0f8c9cd169954b39f167d Signed-off-by: Stefan Reinauer Signed-off-by: Duncan Laurie Reviewed-on: http://review.coreboot.org/871 Tested-by: build bot (Jenkins) Reviewed-by: Duncan Laurie --- src/include/cpu/intel/speedstep.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/include/cpu/intel') diff --git a/src/include/cpu/intel/speedstep.h b/src/include/cpu/intel/speedstep.h index 0fa5244181..00a5b9b87d 100644 --- a/src/include/cpu/intel/speedstep.h +++ b/src/include/cpu/intel/speedstep.h @@ -19,6 +19,9 @@ * MA 02110-1301 USA */ +/* Magic value used to locate speedstep configuration in the device tree */ +#define SPEEDSTEP_APIC_MAGIC 0xACAC + /* MWAIT coordination I/O base address.
