From 2cea1e6b9aa20af4040e87e88f9d4d2017cc2233 Mon Sep 17 00:00:00 2001 From: wbx Date: Wed, 16 Mar 2005 13:50:00 +0000 Subject: [PATCH] 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 --- .../linux/kernel-patches/001-Makefile.bz2 | Bin 854 -> 807 bytes
