From f711bf03a694bc594a610a70251716d425fbe101 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Tue, 25 Jan 2022 19:48:38 -0600 Subject: soc/intel/common/cse: skip heci_init() if HECI1 is disabled If the HECI1 PCI device is disabled, either via devicetree or other method (HAP, me_cleaner), then we don't want/need to program a BAR, set the PCI config, or call heci_reset(), as the latter will result in a 15s timeout delay when booting. Test: build/boot Purism Librem 13v2, verify heci_reset() timeout delay is no longer present.
