The BCM4708 I have, which is probably the first generation which got to the consumer market, is using a ARM Cortex-A9 rev r3p0 and a L2C-310 rev r3p2 L2 cache controller. There are 3 workarounds for known erratas in the Linux kernel which could be activated and will be in this patch. There are currently no workarounds which have to be activated for the L2C-310 rev r3p2 in Linux.

This enables support for systems based on Broadcom IPROC architected SoCs.
|
|
The IPROC complex contains one or more ARM CPUs along with common
|
|
core periperals. Application specific SoCs are created by adding a
|
|
uArchitecture containing peripherals outside of the IPROC complex.
|
|
Currently supported SoCs are Cygnus.

|
integrating several peripheral interfaces including multiple Gigabit

|
|
|
This is a network SoC line mostly used in home routers and
|
|
wifi access points, it's internal name is Northstar.
|
|
This inclused the following SoC: BCM53010, BCM53011, BCM53012,
|
|
BCM53014, BCM53015, BCM53016, BCM53017, BCM53018, BCM4707,
|
|
BCM4708 and BCM4709.
|
|
|
|
Do not confuse this with the BCM4760 which is a totally
|
|
different SoC or with the older BCM47XX and BCM53XX based
|
|
network SoC using a MIPS CPU, they are supported by arch/mips/bcm47xx
