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/drivers/leds/leds-adm5120.c | 361 -------- .../adm5120-2.6/files/drivers/leds/leds-gpio.c | 212 ----- .../files/drivers/mtd/maps/adm5120-flash.c | 574 ------------ .../linux/adm5120-2.6/files/drivers/mtd/myloader.c | 178 ---- .../files/drivers/mtd/nand/rbmipsnand.c | 207 ----- .../adm5120-2.6/files/drivers/net/adm5120sw.c | 625 ------------- .../adm5120-2.6/files/drivers/net/adm5120sw.h | 114 --- .../files/drivers/serial/adm5120_uart.c | 520 ----------- .../files/drivers/usb/host/adm5120-hcd.c | 996 --------------------- 9 files changed, 3787 deletions(-) delete mode 100644 target/linux/adm5120-2.6/files/drivers/leds/leds-adm5120.c delete mode 100755 target/linux/adm5120-2.6/files/drivers/leds/leds-gpio.c delete mode 100644 target/linux/adm5120-2.6/files/drivers/mtd/maps/adm5120-flash.c delete mode 100644 target/linux/adm5120-2.6/files/drivers/mtd/myloader.c delete mode 100644 target/linux/adm5120-2.6/files/drivers/mtd/nand/rbmipsnand.c delete mode 100644 target/linux/adm5120-2.6/files/drivers/net/adm5120sw.c delete mode 100644 target/linux/adm5120-2.6/files/drivers/net/adm5120sw.h delete mode 100644 target/linux/adm5120-2.6/files/drivers/serial/adm5120_uart.c delete mode 100644 target/linux/adm5120-2.6/files/drivers/usb/host/adm5120-hcd.c (limited to 'target/linux/adm5120-2.6/files/drivers') diff --git a/target/linux/adm5120-2.6/files/drivers/leds/leds-adm5120.c b/target/linux/adm5120-2.6/files/drivers/leds/leds-adm5120.c deleted file mode 100644 index 06189371d..000000000 --- a/target/linux/adm5120-2.6/files/drivers/leds/leds-adm5120.c +++ /dev/null @@ -1,361 +0,0 @@ -/* - * $Id$ - * - * ADM5120 GPIO LED devices - * - * Copyright (C) 2007 OpenWrt.org - * Copyright (C) 2007 Gabor Juhos - * - * 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.
