Merge tag 'mips_4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips

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)

   (3) Various cleanups and misc improvements

  More detailed summary:

  Fixes:
   - Fix generic platform's USB_*HCI_BIG_ENDIAN selects (4.9)
   - Fix vmlinuz default build when ZBOOT selected
   - Fix clean up of vmlinuz targets
   - Fix command line duplication (in preparation for Ingenic JZ4770)

  Miscellaneous:
   - Allow Processor ID reads to be to be optimised away by the compiler
     (improves performance when running in guest)
   - Push ARCH_MIGHT_HAVE_PC_SERIO/PARPORT down to platform level to
     disable on generic platform with Ranchu board support
   - Add helpers for assembler macro instructions for older assemblers
   - Use assembler macro instructions to support VZ, XPA & MSA
     operations on older assemblers, removing C wrapper duplication
   - Various improvements to VZ & XPA assembly wrappers
   - Add drivers/platform/mips/ to MIPS MAINTAINERS entry

  Minor cleanups:
   - Misc FPU emulation cleanups (removal of unnecessary include, moving
     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
   - Add DT vendor prefix to GCW (Game Consoles Worldwide)

  Loongson:
   - Add MAINTAINERS entry for Loongson2 and Loongson3 platforms
   - Drop 32-bit support for Loongson 2E/2F devices
   - Fix build failures due to multiple use of 'MEM_RESERVED'"
