+From 31c761c9c1fa91bf4ed83d75dcbc4e426ea2b670 Mon Sep 17 00:00:00 2001
+From: Florian Fainelli <florian@openwrt.org>
+Date: Tue, 18 Jun 2013 16:55:40 +0000
+Subject: [PATCH 2/6] MIPS: BCM63XX: add support for BCM3368 Cable Modem
+
+The Broadcom BCM3368 Cable Modem SoC is extremely similar to the
+existing BCM63xx DSL SoCs, in particular BCM6358, therefore little effort
+in the existing code base is required to get it supported. This patch adds
+support for the following on-chip peripherals:
+
+- two UARTS
+- GPIO
+- Ethernet
+- SPI
+- PCI
+- NOR Flash
+
+The most noticeable difference with 3368 is that it has its peripheral
+register at 0xfff8_0000 we check that separately in ioremap.h. Since
+3368 is identical to 6358 for its clock and reset bits, we use them
+verbatim.
