From 836ae29ee325b1e3d28ff59468cc50913b1e24ce Mon Sep 17 00:00:00 2001 From: stepan Date: Wed, 8 Dec 2010 05:42:47 +0000 Subject: first round name simplification. drop the _ prefix. the prefix was introduced in the early v2 tree many years ago because our old build system "newconfig" could not handle two files with the same name in different paths like /path/to/usb.c and /another/path/to/usb.c correctly. Only one of the files would end up being compiled into the final image. Since Kconfig (actually since shortly before we switched to Kconfig) we don't suffer from that problem anymore. So we could drop the sb700_ prefix from all those filenames (or, the _ prefix in general) - makes it easier to fork off a new chipset - makes it easier to diff against other chipsets - storing redundant information in filenames seems wrong Signed-off-by: Acked-by: Patrick Georgi Acked-by: Peter Stuge git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6149 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/southbridge/nvidia/ck804/pci.c | 94 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 94 insertions(+) create mode 100644 src/southbridge/nvidia/ck804/pci.c (limited to 'src/southbridge/nvidia/ck804/pci.c') diff --git a/src/southbridge/nvidia/ck804/pci.c b/src/southbridge/nvidia/ck804/pci.c new file mode 100644 index 0000000000..044c7100d4 --- /dev/null +++ b/src/southbridge/nvidia/ck804/pci.c @@ -0,0 +1,94 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2004 Tyan Computer + * Written by Yinghai Lu for Tyan Computer. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; version 2 of the License. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
