From 32e06732322765819e5bf54167d3159275f7dfa8 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Fri, 28 Jan 2022 02:05:15 +0530 Subject: soc/intel/common/cse: Rework heci_disable function This patch provides the possible options for SoC users to choose the applicable interface to make HECI1 function disable at pre-boot. `SOC_INTEL_COMMON_BLOCK_HECI_DISABLE_USING_SBI` config is used for disabling heci1 using non-posted sideband write (inside SMM) after FSP-S sets the postboot_sai attribute. Applicable from CNL PCH onwards. `SOC_INTEL_COMMON_BLOCK_HECI_DISABLE_USING_PMC_IPC` config is used for disabling heci1 using PMC IPC command `0xA9`. Applicable from TGL PCH onwards. `SOC_INTEL_COMMON_BLOCK_HECI_DISABLE_USING_PCR` config is used for disabling heci1 using private configuration register (PCR) write. Applicable for SoC platform prior to CNL PCH. Additionally, add PID_CSME0 macro for SKL, Xeon_SP and APL to fix the compilation failure. Finally, rename heci_disable() function to heci1_disable() to make it more meaningful. BUG=none TEST=Able to build and boot brya.
