1892bbcdd4 ARM: bcm: clean up config and build targets
Currently CONFIG_ARCH_BCM_MOBILE is used to select all (both)
Broadcom mobile SoC families.  Instead, use that only as a config
menu switch, and define specific symbols like ARCH_BCM_281XX to
select a particular SoC family.  If ARCH_BCM_MOBILE is selected, all
of the SoCs will be selected by default, but this way each can be
disabled individually as well.

Note that BCM281xx and BCM21664 both require the SMC and L2 cache
control code, so that code will be built based on ARCH_BCM_MOBILE.

ff050ad12c ARM: SoC specific changes
Lots of changes specific to one of the SoC families. Some that
 stick out are:
 
 * mach-qcom gains new features, most importantly SMP support for
   the newer chips (Stephen Boyd, Rohit Vaswani)
 * mvebu gains support for three new SoCs: Armada 375, 380 and 385
   (Thomas Petazzoni and Free-electrons team)
 * SMP support for Rockchips (Heiko Stübner)
 * Lots of i.MX changes (Shawn Guo)
 * Added support for BCM5301x SoC (Hauke Mehrtens)
 * Multiplatform support for Marvell Kirkwood and Dove
   (Andrew Lunn and Sebastian Hesselbarth doing the final part
   of a long journey)
 * Unify davinci platforms and remove obsolete ones (Sekhar Nori,
   Arnd Bergmann)

This patch adds support for the BCM5301X/BCM470X SoCs with an ARM CPUs.
Currently just booting to a shell is working and nothing else, no
Ethernet, wifi, flash, ...
I have some pending patches to make Ethernet work for this device.
Mostly device tree support for bcma is missing.

This SoC is used in small office and home router with Broadcom SoCs
it's internal name is Northstar. This code should support the BCM4707,
BCM4708, BCM4709, BCM53010, BCM53011 and BCM53012 SoC. It uses one or
two ARM Cortex A9 Cores, some highlights are 2 PCIe 2.0 controllers,
4 Gigabit Ethernet MACs and a USB 3.0 host controller.

This SoC uses a dual core CPU, but this is currently not implemented.
More information about this SoC can be found here:

Updates from V4:
- Switch code to use CLOCKSOURCE_OF_DECLARE

Updates from V3:
- Migrate to 3.9 timer framework updates

Updates from V2:
- prepend static fns + fields with kona_

Updates from V1:
- Rename bcm_timer.c to bcm_kona_timer.c
- Pull .h into bcm_kona_timer.c
- Make timers static
- Clean up comment block
- Switched to using clockevents_config_and_register
- Added an error to the get_timer loop if it repeats too much
- Added to Documentation/devicetree/bindings/arm/bcm/bcm,kona-timer.txt
- Added missing readl to timer_disable_and_clear

Note: bcm,kona-timer was kept as the 'compatible' field to make it
specific enough for when there are multiple bcm timers (bcm,timer is

8ac49e0485 Add support for generic BCM SoC chipsets
In order to start upstreaming Broadcom SoC support, create
a starting hierarchy, arch and dts files.
The first support SoC family that is planned is the
BCM281XX (BCM11130/11140/11351/28145/28155) family of dual A9 mobile
SoC cores.
This code is just the skeleton code for get the machine upstreamed. It
has been made MULTIPLATFORM compatible.
Next steps
----------
Upstream a basic set of drivers - sufficient for a console boot to
ramdisk. These will includer timer, gpio, i2c drivers.
After this basic set, we will proceed with a more comprehensive set
of drivers for the 281XX SoC family.

v2 patch mods
--------
 - Remove l2x0_of_init call as there were problems with the code.
   A separate patch will be submitted with cache init code
 - Rename capri files and refs to bcm281xx-based names
 - Add bcm281xx binding doc
 - various misc cleanups

v3 patch mods
-------------
 - Remove extra #include lines
 - Remove remaining references to capri
 - dt uart chipset string added
 - cleaned up chip # references

v4 patch mods
-------------
 - swap order of compatible definitions for uart
 - fix typo

v5 patch mods
-------------
 - Rename bcm281xx to bcm11351 in dts+code,
   leaving references to bcm281xx only in help+comments.

v6 patch mods
-------------
 - fix typo in uart 'compatible' string
