Hi all,

I'm taking over the latest resubmission of this patch series.
There are a few moderate changes for v8 (noted below), but we
are waiting mostly for an Ack for the reboot driver.

This patchset contains the board support package for the
Broadcom BCM7445 ARM-based SoC [1]. These changes contain a
minimal set of code needed for a BCM7445-based board to boot
the Linux kernel.

These changes heavily leverage the OF/devicetree framework. The
machine is also built into the multi-platform ARMv7 image.

Changes are also available here:

v8:
- rebase to v3.16-rc6
- convert SMP bringup to use CPU_METHOD_OF_DECLARE
- add MAINTAINERS entries
- select a few new drivers for the ARCH_BRCMSTB platform

v7 (https://lkml.org/lkml/2014/2/26/133):
- rebase to v3.14-rc4
- detect and apply ARM erratum 798181 to Brahma15 CPUs
- split-up bcm7445.dts into a common dtsi and board-specific dts

v6 (https://lkml.org/lkml/2014/2/3/493):
- rebased to v3.14-rc1
- utilize common APIs for handling CPU power-down
- drop deprecated __cpuinit attributes

v5 (https://lkml.org/lkml/2014/1/21/640):
- rebased to v3.13 tag
- make UART DT node a child of 'rdb' node

v4 (https://lkml.org/lkml/2014/1/17/455):
- make a reboot driver and put it in the drivers folder
- rework DT bindings to leverage 'syscon'
- rework BSP code to use 'syscon' for all register mappings
- misc. tweaks per suggestions from v3

v3 (https://lkml.org/lkml/2014/1/14/696):
- rebased to v3.13-rc8
- switched to using 'multi_v7_defconfig'
- eliminated dependence on compile-time peripheral register access
- moved DT node iomap out from 'init_early'
- misc. minor cleanups from mailing-list discussion for v2

v2 (https://lkml.org/lkml/2013/11/26/570):
- rebased to v3.13-rc1
