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.
