From 31c761c9c1fa91bf4ed83d75dcbc4e426ea2b670 Mon Sep 17 00:00:00 2001

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.
