[PATCH v8 0/4] ARM: BCM5301X: initial support for the BCM5301X/BCM470X SoCs with ARM CPU

[Hauke Mehrtens]

This adds initial support for Broadcom network SoC from the BCM5301X 
and BCM470X line.

I do not have any documentation, only the vendor source code published 
by Asus and Netgear to conform with the GPL, it would be nice to get 
some documentation for this Soc like this
https://www.broadcom.com/collateral/pg/440X-PG02-R.pdf
for the Broadcom BCM440X Ethernet controller.

With some additional patches I got Ethernet working with ~250 MBit/s.

A bootlog can be found here:

This is based on 3.14-rc1.

Christian Daudt could you please take these patches.

Changes since v7:
 * reorder debug options
 * rebase on 3.14-rc1

Changes since v6:
 * rebase on arm-soc.git branch next/soc
 * use ranges in dts files for SoC blocks

Changes since v5:
 * restructured the dts files, own file for the SoC family, the SoC and
   the device

Changes since v4:
 * removed bcm5301x_timer_init(), this function is not needed
 * removed GENERIC_TIME this is dead
 * made fault handler check for code and just catch the first fault.

Changes since v3:
 * rebase on Linus 3.13-rc7
 * split the workaround into an own patch
 * add L2 cache controller to Device tree
 * rename config option
 * add local-timer and SCU entry to device tree

Changes since v2:
 * use vendor prefix brcm
 * move code to arch/arm/mach-bcm/
 * cleanup arch/arm/mach-bcm/bcm5301x.c
 * rename to bcm5301x
 * split into more patches

Changes since v1:
 * add file Documentation/devicetree/bindings/arm/bcm4708.txt
 * rename bcm5301x to bcm4708 in dts files
 * use preprocessor includes in dts file
 * add CONFIG_ARCH_BCM53XX to multi_v7_defconfig
 * remove init_machine callback
 * rename vendor prefix from brcm to bcm
 * split into two patches
