From c49efa365e1e1f07db8f208f4a63f27ca81e290d Mon Sep 17 00:00:00 2001 From: Jeremy Compostella Date: Mon, 13 Mar 2023 10:55:21 -0700 Subject: mb/google/brya: 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 20 to 30 ms on brya0. BUG=b:268546941 BRANCH=firmware-brya-14505.B TEST=Tests on brya0 with `SOC_INTEL_CSE_SEND_EOP_ASYNC' show End-Of-Post after PCI initialization and EOP message received at `BS_PAYLOAD_BOOT'.
