From 4f531230a3c9c8984c5a8e8b38874be7f608f2d1 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/openwrt@379 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- package/linux/kernel-source/include/sbmemc.h | 147 +++++++++++++++++++++++++++ 1 file changed, 147 insertions(+) create mode 100644 package/linux/kernel-source/include/sbmemc.h (limited to 'package/linux/kernel-source/include/sbmemc.h') diff --git a/package/linux/kernel-source/include/sbmemc.h b/package/linux/kernel-source/include/sbmemc.h new file mode 100644 index 000000000..d0002ac34 --- /dev/null +++ b/package/linux/kernel-source/include/sbmemc.h @@ -0,0 +1,147 @@ +/* + * BCM47XX Sonics SiliconBackplane DDR/SDRAM controller core hardware definitions. + * + * 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.
