From 17c7b6c3fdc48301e50d22cc6138ede16bd1be24 Mon Sep 17 00:00:00 2001 From: nbd Date: Thu, 6 Sep 2007 16:27:37 +0000 Subject: strip the kernel version suffix from target directories, except for brcm-2.4 (the -2.4 will be included in the board name here). CONFIG_LINUX__ becomes CONFIG_TARGET_, same for profiles. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@8653 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../adm5120-2.6/files/arch/mips/adm5120/irq.c | 203 --------------------- 1 file changed, 203 deletions(-) delete mode 100644 target/linux/adm5120-2.6/files/arch/mips/adm5120/irq.c (limited to 'target/linux/adm5120-2.6/files/arch/mips/adm5120/irq.c') diff --git a/target/linux/adm5120-2.6/files/arch/mips/adm5120/irq.c b/target/linux/adm5120-2.6/files/arch/mips/adm5120/irq.c deleted file mode 100644 index 8d6fbe6a3..000000000 --- a/target/linux/adm5120-2.6/files/arch/mips/adm5120/irq.c +++ /dev/null @@ -1,203 +0,0 @@ -/* - * $Id$ - * - * ADM5120 specific interrupt handlers - * - * Copyright (C) 2007 Gabor Juhos - * Copyright (C) 2007 OpenWrt.org - * - * 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; either version 2 - * of the License, or (at your option) any later version. - * - * 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.
