From 2cea1e6b9aa20af4040e87e88f9d4d2017cc2233 Mon Sep 17 00:00:00 2001 From: wbx Date: Wed, 16 Mar 2005 13:50:00 +0000 Subject: add all source code from linksys/broadcom which is free, to cvs for better maintainence inside openwrt. this gives us the ability to better support different hardware models, without changing any external tar-balls. only et.o and wl.o is missing and is fetched from my webserver. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@379 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../kernel-source/drivers/pcmcia/bcm4710pcmcia.h | 118 +++++++++++++++++++++ 1 file changed, 118 insertions(+) create mode 100644 openwrt/package/linux/kernel-source/drivers/pcmcia/bcm4710pcmcia.h (limited to 'openwrt/package/linux/kernel-source/drivers/pcmcia/bcm4710pcmcia.h') diff --git a/openwrt/package/linux/kernel-source/drivers/pcmcia/bcm4710pcmcia.h b/openwrt/package/linux/kernel-source/drivers/pcmcia/bcm4710pcmcia.h new file mode 100644 index 000000000..42a7463bd --- /dev/null +++ b/openwrt/package/linux/kernel-source/drivers/pcmcia/bcm4710pcmcia.h @@ -0,0 +1,118 @@ +/* + * + * bcm47xx pcmcia driver + * + * Copyright 2004, Broadcom Corporation + * All Rights Reserved. + * + * THIS SOFTWARE IS OFFERED "AS IS", AND BROADCOM GRANTS NO WARRANTIES OF ANY + * KIND, EXPRESS OR IMPLIED, BY STATUTE, COMMUNICATION OR OTHERWISE.
