From 9e5bc74cc7c2a6ced08163418299cc753b8357f0 Mon Sep 17 00:00:00 2001 From: Felix Singer Date: Tue, 13 Oct 2020 18:05:03 +0200 Subject: libpayload/arch/x86: Introduce pacc pointer in sysinfo_t struct Currently, the PCI bus gets scanned multiple times for various reasons (e.g. to read the device class). Therefore, and in preparation to CB:46416, introduce the pacc pointer in the sysinfo_t struct and scan the PCI bus while gathering system information.
