From 913684cd2e0ec26f443fc128de7dfc18de49da7b Mon Sep 17 00:00:00 2001 From: York Yang Date: Wed, 5 Oct 2016 10:19:40 -0700 Subject: soc/intel/fsp_broadwell_de: Fix system hang when timestamp is enabled When timestamp is enabled, the system hangs because the timestamp data is not yet available. Add a temporary work around that starts the timestamp after the FspInit() making this data available. Verified on Intel Camelback Mountain CRB and ensured that system can boot to payload with timpstamp feature enabled.
