MIPS: Regenerate defconfigs
A couple of patches have come up recently to remove particular instances
of obsolete Kconfig symbols from defconfigs. Rather than doing this
piecemeal, simply regenerate them all.

209b43759d ssb: Remove SSB_WARN_ON, SSB_BUG_ON and SSB_DEBUG
Use the standard WARN_ON instead.
If a small kernel is desired, WARN_ON can be disabled globally.

Also remove SSB_DEBUG. Besides WARN_ON it only adds a tiny debug check.
Include this check unconditionally.

MIPS: generic: Remove input symbols from defconfig
generic_defconfig explicitly disables CONFIG_INPUT_MOUSEDEV,
CONFIG_INPUT_KEYBOARD & CONFIG_INPUT_MOUSE which results in warnings
when merging board config fragments if any of them require these
options. This is the case for the ranchu board, which means we've had
the following warning when configuring for generic platform targets
since commit f2d0b0d5c1 ("MIPS: ranchu: Add Ranchu as a new
generic-based board"):

  $ make ARCH=mips 32r2el_defconfig
  Using ./arch/mips/configs/generic_defconfig as base
  Merging arch/mips/configs/generic/32r2.config
  Merging arch/mips/configs/generic/el.config
  Merging ./arch/mips/configs/generic/board-sead-3.config
  Merging ./arch/mips/configs/generic/board-ranchu.config
  Value of CONFIG_INPUT_KEYBOARD is redefined by fragment ./arch/mips/configs/generic/board-ranchu.config:
  Previous value: # CONFIG_INPUT_KEYBOARD is not set
  New value: CONFIG_INPUT_KEYBOARD=y

  Merging ./arch/mips/configs/generic/board-ni169445.config
  Merging ./arch/mips/configs/generic/board-boston.config

  Merging ./arch/mips/configs/generic/board-xilfpga.config
  scripts/kconfig/conf  --olddefconfig Kconfig
  #
  # configuration written to .config
  #

Resolve this by removing mention of the CONFIG_INPUT_* Kconfig symbols
from generic_defconfig, allowing them to take their default values &
allowing board config fragments to enable them without warnings.

This may be problematic if CONFIG_ARCH_MIGHT_HAVE_PC_SERIO is ever
enabled for CONFIG_MIPS_GENERIC=y configurations, but for now that isn't
the case so we can worry about that if & when it happens.

MIPS: qi_lb60: Enable the jz4740-wdt driver
The watchdog is an useful piece of hardware, so there's no reason not to
enable it.

Besides, this is important for restart to work after the change in the
next commit.

This commit enables the Kconfig option in the qi_lb60 defconfig.

Pull MIPS updates from James Hogan:
 "These are the main MIPS changes for 4.16.

  Rough overview:

   (1) Basic support for the Ingenic JZ4770 based GCW Zero open-source
       handheld video game console

   (2) Support for the Ranchu board (used by Android emulator)

     macros to common header, checkpatch and sparse fixes)
   - Remove duplicate assignment of core in play_dead()
   - Remove duplication in watchpoint handling
   - Remove mips_dma_mapping_error() stub
   - Use NULL instead of 0 in prepare_ftrace_return()
   - Use proper kernel-doc Return keyword for
     __compute_return_epc_for_insn()
   - Remove duplicate semicolon in csum_fold()

  Platform support:

  Broadcom:
   - Enable ZBOOT on BCM47xx

  Generic platform:
   - Add Ranchu board support, used by Android emulator
   - Fix machine compatible string matching for Ranchu
   - Support GIC in EIC mode

  Ingenic platforms:
   - Add DT, defconfig and other support for JZ4770 SoC and GCW Zero
   - Support dynamnic machine types (i.e. JZ4740 / JZ4770 / JZ4780)
   - Add Ingenic JZ4770 CGU clocks
   - General Ingenic clk changes to prepare for JZ4770 SoC support
   - Use common command line handling code

MIPS: ranchu: Add Ranchu as a new generic-based board
Provide amendments to the MIPS generic platform framework so that
the new generic-based board Ranchu can be chosen to be built.

The Ranchu board is intended to be used by Android emulator. The name
"Ranchu" originates from Android development community. "Goldfish" and
"Ranchu" are terms used for two generations of virtual boards used by
Android emulator. The name "Ranchu" is a newer one among the two, and
this patch deals with Ranchu. However, for historical reasons, some
devices/drivers still contain the name "Goldfish".

MIPS Ranchu machine includes a number of Goldfish devices. The support
for Virtio devices is also included. Ranchu board supports up to 16
Virtio devices which can be attached using Virtio MMIO Bus. This is
summarized in the following picture:

 "This is the main pull request for 4.14 for MIPS; below a summary of
  the non-merge commits:

  CM:
   - Rename mips_cm_base to mips_gcr_base
   - Specify register size when generating accessors
   - Use BIT/GENMASK for register fields, order & drop shifts
   - Add cluster & block args to mips_cm_lock_other()

  CPC:
   - Use common CPS accessor generation macros
   - Use BIT/GENMASK for register fields, order & drop shifts
   - Introduce register modify (set/clear/change) accessors
   - Use change_*, set_* & clear_* where appropriate
   - Add CM/CPC 3.5 register definitions
   - Use GlobalNumber macros rather than magic numbers
   - Have asm/mips-cps.h include CM & CPC headers
   - Cluster support for topology functions
   - Detect CPUs in secondary clusters

  CPS:
   - Read GIC_VL_IDENT directly, not via irqchip driver

  DMA:
   - Consolidate coherent and non-coherent dma_alloc code
   - Don't use dma_cache_sync to implement fd_cacheflush

  FPU emulation / FP assist code:
   - Another series of 14 commits fixing corner cases such as NaN
     propgagation and other special input values.
   - Zero bits 32-63 of the result for a CLASS.D instruction.
   - Enhanced statics via debugfs
   - Do not use bools for arithmetic. GCC 7.1 moans about this.
   - Correct user fault_addr type

  Generic MIPS:
   - Enhancement of stack backtraces
   - Cleanup from non-existing options
   - Handle non word sized instructions when examining frame
   - Fix detection and decoding of ADDIUSP instruction

   - Refactor handling of stack pointer in get_frame_info
   - Remove unreachable code from force_fcr31_sig()
   - Convert to using %pOF instead of full_name
   - Remove the R6000 support.
   - Move FP code from *_switch.S to *_fpu.S
   - Remove unused ST_OFF from r2300_switch.S
   - Allow platform to specify multiple its.S files
   - Add #includes to various files to ensure code builds reliable and
     without warning..
   - Remove __invalidate_kernel_vmap_range

5cbf968803 MIPS: Make CONFIG_MIPS_MT_SMP default y
On systems that support MT ASE multithreading (ie. VPEs) we are very
likely to want to include that support as default. Rather than setting
it in various defconfigs, simply make CONFIG_MIPS_MT_SMP default y such
that systems which select CONFIG_SYS_SUPPORTS_MULTITHREADING get it by
default.

As well as allowing us to remove the selection of CONFIG_MIPS_MT_SMP
from various defconfigs, this also allows the generated generic
defconfigs which derive from generic_defconfig to automatically gain
support for MT ASE SMP when building for a suitable (pre-MIPSr6) ISA.

For malta_kvm_guest_defconfig CONFIG_MIPS_MT_SMP is explicitly disabled
since enabling SMP implicitly disables CONFIG_KVM_GUEST, which depends
on CONFIG_BROKEN_ON_SMP.

9e111ee7c3 MIPS: NI 169445: Only include in 32r2el kernels
The NI 169445 board uses a little endian MIPS32r2 CPU, and therefore
including board support in kernels that are unable to run on such a CPU
is pointless.

Specify requirements in the board config fragment that cause the NI
169445 board support to only be included in generic kernels that target
little endian MIPS32r2 CPUs.

For example, NI 169445 support will be included when configuring using
32r2el_defconfig but not when using 64r6_defconfig.

The MIPS SEAD-3 development board has only ever been used with 32 bit
CPUs, so including support for it in 64 bit kernels is wasteful since
those kernels will never run on a SEAD-3.

Specify a requirement in the SEAD-3 board config fragment that ensures
the board support is only included in 32 bit kernels, by checking that
CONFIG_32BIT=y.

Add support for the MIPS Boston development board to generic kernels,
which essentially amounts to:

  - Adding the device tree source for the MIPS Boston board.

  - Adding a Kconfig fragment which enables the appropriate drivers for
    the MIPS Boston board.

With these changes in place generic kernels will support the board by
default, and kernels with only the drivers needed for Boston enabled can
be configured by setting BOARDS=boston during configuration. For
example:

  $ make ARCH=mips 64r6el_defconfig BOARDS=boston
