From: "Agyeman, Prince" <prince.agye...@intel.com> REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2409
Updated WhiskeylakeURvp PCDs to enable FSP/BL stack sharing. This fixes the boot failure seen with the latest Coffee Lake (CFL) FSP binary (v 7.0.68.41). Cc: Chasel Chiu <chasel.c...@intel.com> Cc: Nate DeSimone <nathaniel.l.desim...@intel.com> Cc: Michael Kubacki <michael.a.kuba...@intel.com> Co-authored-by: Michael Kubacki <michael.a.kuba...@intel.com> Signed-off-by: Prince Agyeman <prince.agye...@intel.com> Reviewed-by: Chasel Chiu <chasel.c...@intel.com> --- Notes: 1. Michael Kubacki is taking over patch ownership since Prince is out of office. V3 Change: - Changed the value of PcdPeiTemporaryRamStackSize to 0x30000 to exceed the minimum stack size specified in the Coffee Lake FSP Integration Guide (160KB / 0x28000) with some padding. V2 Change: - The value of PcdPeiTemporaryRamStackSize was changed from 0x40000 to 0x28000 to exactly meet the minimum stack size specified in the Coffee Lake FSP Integration Guide. Note that the memory initialization code in the FSP previously exceeded the available stack size.
