Subject: [PATCH v7 0/9] ARM: brcmstb: Add Broadcom STB SoC support

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.

v7:
- 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
- fix ordering of debug UART entries

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
- moved implementation to 'mach-bcm' folder
- added CPU init for B16RM

v1:
- initial submission
