From be667ba94822877036f6c80992554ed32314a1f2 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Wed, 14 Sep 2022 14:29:52 +0100 Subject: [pci] Add support for the Enhanced Configuration Access Mechanism (ECAM) The ACPI MCFG table describes a direct mapping of PCI configuration space into MMIO space. This mapping allows access to extended configuration space (up to 4096 bytes) and also provides for the existence of multiple host bridges. Add support for the ECAM mechanism described by the ACPI MCFG table, as a selectable PCI I/O API alongside the existing PCI BIOS and Type 1 mechanisms.
