From 79670e1e13de9f49a610f903feaedc3e8f60d632 Mon Sep 17 00:00:00 2001 From: nbd Date: Sat, 18 Oct 2008 21:43:30 +0000 Subject: change the way ./files* and the generic kernel files are applied. ./files now applies to *ALL* kernel versions, and is copied along with ./files-* - this gets rid of quite a bit of redundancy in the extra kernel drivers. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@13010 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../generic-2.6/files/drivers/ssb/driver_extif.c | 129 --------------------- 1 file changed, 129 deletions(-) delete mode 100644 target/linux/generic-2.6/files/drivers/ssb/driver_extif.c (limited to 'target/linux/generic-2.6/files/drivers/ssb/driver_extif.c') diff --git a/target/linux/generic-2.6/files/drivers/ssb/driver_extif.c b/target/linux/generic-2.6/files/drivers/ssb/driver_extif.c deleted file mode 100644 index fe55eb8b0..000000000 --- a/target/linux/generic-2.6/files/drivers/ssb/driver_extif.c +++ /dev/null @@ -1,129 +0,0 @@ -/* - * Sonics Silicon Backplane - * Broadcom EXTIF core driver - * - * Copyright 2005, Broadcom Corporation - * Copyright 2006, 2007, Michael Buesch - * Copyright 2006, 2007, Felix Fietkau - * Copyright 2007, Aurelien Jarno - * - * Licensed under the GNU/GPL.
