soc/intel/apollolake: Enable logging for wake sources in S0ix
This change adds GSMI callback elog_gsmi_cb_platform_log_wake_source to enable wake source logging from S0ix on APL/GLK. Additionally, elog.c is added to smm stage. BUG=b:79449585 TEST=Verified that S0ix entry/exit events are added to eventlog: =========== Power button ============ 59 | 2018-06-25 14:01:11 | S0ix Enter 60 | 2018-06-25 14:01:30 | S0ix Exit 61 | 2018-06-25 14:02:00 | Wake Source | Power Button | 0 =========== Lid open ================ 62 | 2018-06-25 14:02:36 | S0ix Enter 63 | 2018-06-25 14:02:56 | S0ix Exit 64 | 2018-06-25 14:03:26 | Wake Source | GPE # | 15 65 | 2018-06-25 14:03:32 | Wake Source | GPE # | 65 66 | 2018-06-25 14:03:37 | EC Event | Lid Open =========== Trackpad ================ 67 | 2018-06-25 14:04:20 | S0ix Enter 68 | 2018-06-25 14:04:33 | S0ix Exit 69 | 2018-06-25 14:05:03 | Wake Source | GPE # | 15 70 | 2018-06-25 14:05:08 | Wake Source | GPE # | 66 Change-Id: I005de58c73d00dc9d7e64f1459f6d786792b94db Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/27234 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Justin TerAvest <teravest@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
