From 6f66f414a0907f79abf492cd9eca839c0849c7f6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Thu, 1 Dec 2016 22:08:18 +0200 Subject: PCI ops: MMCONF_SUPPORT_DEFAULT is required MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Doing PCI config operations via MMIO window by default is a requirement, if supported by the platform. This means chipset or CPU code must enable MMCONF operations early in bootblock already, or before platform-specific romstage entry. Platforms are allowed to have NO_MMCONF_SUPPORT only in the case it is actually not implemented in the silicon.
