From 3879334ca0d73c84a03416a73fcf52c95f39ba6b Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Wed, 19 Apr 2023 18:38:03 +0530 Subject: mb/google/rex: Enable asynchronous End-Of-Post Set the `SOC_INTEL_CSE_SEND_EOP_ASYNC' flag to request End-Of-Post right after PCI enumeration and handle the command response at `BS_PAYLOAD_BOOT'. With these settings we have observed a boot time reduction of about 100ms on google/rex. TEST=Tests on google/rex with `SOC_INTEL_CSE_SEND_EOP_ASYNC' show End-Of-Post after PCI initialization and EOP message received at `BS_PAYLOAD_BOOT'.
