From c319bab3cd416d85330774f9974b41fcb49075a7 Mon Sep 17 00:00:00 2001 From: Lijian Zhao Date: Sat, 8 Jul 2017 18:16:13 -0700 Subject: intel/cannonlake_rvp: Split RVP boards and SPD Add both Cannonlake U DDR4 RVP and Cannonlake Y LPDDR4 RVP support. Implement SPD entry to FSPM for both platforms, seperated platform specific DQ/DQS/Rcomp input to FSPM as well.
