Platform PSR wake options vbt version KBL/CFL/WHL All(205+) BXT Uses old interpretation. CNL/ICL+ All(205+) GLK All(205+) SKL All PV releases (Check for 205+ might help but cannot be foolproof) We will continue with newer interpretation for SKL from 205. v2: Jani Keep the bdb version check. v3: Apply newer version for skl from 205+(DK). Add (version check && platform list) (Jani). Add bdb version for each platform in commit message(DK).
