In order to have a unique .c file for all pxa variants device-tree
definitions, all the initialization functions for MACHINE_START and
DT_MACHINE_START have been put together into generic.h.
The alternative would have been one pxaXXX-dt.c file per variant.
The move is necessary because each include/mach/pxaXXX.h includes the
variant register descriptions which intersects and conflicts one with
each other.
The change is a preparation for pxa-dt.c to support multiple pxa,

ARM: shmobile: Add early debugging support using SCIF(A)
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.

broke allmodconfig like this:
>> arch/arm/include/asm/cmpxchg.h:114:2: error: #error
"SMP is not supported on this platform"
(etc)
This is due to the fact that as we turned on multiplatform
for the Integrator, this enabled a lot of non-applicable
CPU's to be selected for its multiplatform images, due to
a lot of "depends on ARCH_INTEGRATOR" restrictions in
arch/arm/mm/Kconfig for the different ARM CPU types.
Fix this by restricting the CPU selections to respective
multiplatform config, which now becomes a subset of the
possible Integrator configurations, or alternatively the
non-multiplatform config plus ARCH_INTEGRATOR, i.e.:
if (!ARCH_MULTIPLATFORM || ARCH_MULTI_Vx) &&
(ARCH_INTEGRATOR || ARCH_FOO ...)
Since the Integrator has been converted to multiplatform,
this will often take the short form:
if (ARCH_MULTI_Vx && ARCH_INTEGRATOR)
If no other non-multiplatform platforms are elegible.

CPU logic power state is never programmed in either the initialization
or the suspend/resume logic, instead, we depend on mpuss to program this
properly. However, this leaves CPU logic power state indeterminate and
most probably in reset configuration (If bootloader or other similar
software have'nt monkeyed with the register). This can make powerstate=
RET be either programmed for CSWR (logic=ret) or OSWR(logic = OFF) and
in OSWR, there can be context loss when the code does not expect it.
To prevent all these confusions, just support clearly ON, INA, CSWR,
OFF which is the intent of the existing code by explicitly programming
logic state.
NOTE: since this is a hot path (using in cpuidle), the exit path just
programs powerstate (logic state is immaterial when powerstate is ON).
Without doing this, we end up with lockups when CPUs enter OSWR and
multiple blocks loose context, when we expect them to hit CSWR.

ARM: rockchip: add basic smp support for rk3288
This patch add basic rk3288 smp support.
Only cortex-A9 need invalid L1, A7/A12/A15/A17 should not invalid L1, since
for A7/A12/A15, the invalidation would be taken as clean and invalidate.
If you use the software manual invalidation instead of hardware invalidation
(assert l1/l2rstdisable during reset) after reset, there is tiny change that
some cachelines would be in dirty and valid state after reset(since the ram
content would be random value after reset), then the unexpected clean might
lead to system crash.
It is a known issue for the A12/A17 MPCore multiprocessor that the active
processors might be stalled when the individual processor is powered down,
we can avoid this prolbem by softreset the processor before power it down.

The pmu register space is - like the GRF - shared by quite some peripherals.
On the rk3188 and rk3288 even parts of the pinctrl are living there.
Therefore we normally shouldn't map it a second time when the syscon
does this already.
Therefore convert the cpu power-domain handling to access the pmu via a
regmap and at first try to get it via the syscon interface.
Getting this syscon will only fail if the pmu node does not have the
"syscon" compatible and thus does not get shared with other drivers.
In this case we map it like before and create the necessary regmap on
top of it.

- A regression from 3.16 which was noticed in 3.17. With the
restructuring of the m25p80.c driver and the SPI NOR library
framework, we omitted proper listing of the SPI device IDs. This
means m25p80.c wouldn't auto-load (modprobe) properly when built as
a module. For now, we duplicate the device IDs into both modules.
- The OMAP / ELM modules were depending on an implicit link ordering.
Use deferred probing so that the new link order (in 3.18-rc) can
still allow for successful probing.
