Footbridge has two debug ports that are handled a bit differently:
The 8250 port uses the normal debug/8250.S implementation that is shared
with a lot of other platforms, but it relies on the DEBUG_UART_8250
option to be turned on automatically instead of being selected by
DEBUG_FOOTBRIDGE_COM1 as we do for most other platforms. I'm changing
this to use a 'select' and change the dependency to the debug symbol
rather than the platform symbol for consistency.
The DC21285 UART has a separate top-level option, and relies on
the traditional include/mach/debug-macro.S method. With the s3c64xx
multiplatform series queued up for 4.5, it is now the last one that does
this, so by moving this file to include/debug/dc21285.S, we can get
all platforms to do things the same way.

Instead of having to add a new configuration option each time support for
new SoC is added, use CONFIG_DEBUG_UART_PHYS. For now,
CONFIG_DEBUG_UART_VIRT is automatically computed.

The i.MX SoC changes for 4.3:
- Add i.MX6 Ultralite SoC support, which is the newest addition to
i.MX6 family. It integrates a single Cortex-A7 core and a power
management module that reduces the complexity of external power
supply and simplifies power sequencing.
- Change SNVS RTC driver to use syscon interface for register access,
and add SNVS power key driver support.
- Add a second clock for mxc rtc driver, and support device tree probe
for the driver.
- Add FEC MAC reference clock and phy fixup initialization for i.MX6UL
platform.

Pull ARM SoC platform changes from Olof Johansson:
"New and updated SoC support. Also included are some cleanups where
the platform maintainers hadn't separated cleanups from new developent
in separate branches.
Some of the larger things worth pointing out:
- A large set of changes from Alexandre Belloni and Nicolas Ferre
preparing at91 platforms for multiplatform and cleaning up quite a
bit in the process.
- Removal of CSR's "Marco" SoC platform that never made it out to the
market. We love seeing these since it means the vendor published
support before product was out, which is exactly what we want!
New platforms this release are:
- Conexant Digicolor (CX92755 SoC)
- Hisilicon HiP01 SoC
- CSR/sirf Atlas7 SoC
- ST STiH418 SoC
- Common code changes for Nvidia Tegra132 (64-bit SoC)
We're seeing more and more platforms having a harder time labelling
changes as cleanups vs new development -- which is a good sign that
we've come quite far on the cleanup effort. So over time we might
start combining the cleanup and new-development branches more"

Add serial port debug macros for the SCIF(A) serial ports.
This includes all supported shmobile SoCs, except for EMEV2.
The configuration logic (both Kconfig and #ifdef) is more complicated than
one would expect, for several reasons:
1. Not all SoCs have the same serial devices, and they're not always
at the same addresses.
2. There are two different types: SCIF and SCIFA. Fortunately they can
easily be distinguished by physical address.
3. Not all boards use the same serial port for the console.
The defaults correspond to the boards that are supported in
mainline. If you want to use a different serial port, just change
the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt.
4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual
address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END
= 0xff000000, and must not conflict with the 2 MiB reserved region
at PCI_IO_VIRT_BASE = 0xfee00000.
- On SoCs not using the legacy machine_desc.map_io(),
debug_ll_io_init() is called by the ARM core code.
- On SoCs using the legacy machine_desc.map_io(),
debug_ll_io_init() must be called explicitly. Calls are added
for r8a7740, r8a7779, sh7372, and sh73a0.
This was derived from the r8a7790 version by Laurent Pinchart.

Separate Qualcomm low-level debugging UART to two options.
DEBUG_MSM_UART is used in earlier non-multi platform arches,
like MSM7X00A, QSD8X50 and MSM7X30.
DEBUG_QCOM_UARTDM is used in multi-plafrom arches and have
embedded data mover.
Make DEBUG_UART_PHYS and DEBUG_UART_BASE user adjustable by
Kconfig menu.

Virtual address have to have the same offset within
a 2MB aligned section of virtual/phycial address space.
Fix uart0 virtual address to be align with physical one.
Also remove UART_SIZE which is completely unused.

Add choice for low-level debug UART. Similar to i.MX6, there is a
numeric configuration, valid choices are 0 to 3.
Note that the kernel assumes that the boot loader initialized clock
properly.

Pull ARM SoC late cleanups from Arnd Bergmann:
"These could not be part of the first cleanup branch, because they
either came too late in the cycle, or they have dependencies on other
branches. Important changes are:
- The integrator platform is almost multiplatform capable after some
reorganization (Linus Walleij)
- Minor cleanups on Zynq (Michal Simek)
- Lots of changes for Exynos and other Samsung platforms, including
further preparations for multiplatform support and the clocks
bindings are rearranged"

Pull ARM SoC cleanups from Arnd Bergmann:
"These cleanup patches are mainly move stuff around and should all be
harmless. They are mainly split out so that other branches can be
based on top to avoid conflicts.
Notable changes are:
- We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used (Uwe Kleine-König)
- The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new
hardware support without regressions (Kumar Gala)
- A rework of some of the Kconfig logic to simplify multiplatform
support (Rob Herring)
- Samsung Exynos gets closer to supporting multiplatform (Sachin
Kamat and others)
- mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
- at91 gains some common clock framework support (Alexandre Belloni,
Jean-Jacques Hiblot and other French people)"

In a combined ARMv6/v7 kernel, we cannot use the
movt/movw instructions to load an immediate, as they
are not valid on ARMv6.
This changes the file to use an indirect load instead,
as lots of other implementations do.
