From 647e34dbe547bcd7bb3990d138b5c6906ea935e8 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Thu, 11 Feb 2016 08:36:50 +0100 Subject: device/pci_rom: Rename missleading ON_DEVICE_ROM_RUN The Kconfig option "ON_DEVICE_ROM_RUN" suggests that PCI Option ROMs are run, but in fact it only controls the loading of PCI based Option ROMs. At the moment coreboot only executes Option ROMs if they are VGA Options ROMs and the VGA Option ROM execution flag is enabled. Setting ON_DEVICE_ROM_RUN with VGA Option ROM execution disabled has no effect. Clarify that this flag controls the loading behaviour and not the execution behaviour.
