MIPS changes for 4.16
Hi Linus,
Here are the main MIPS changes for 4.16. Again most of the patches have been gathered in the last few weeks of the 4.15 cycle, with mainly fixes since then, so there's not a whole lot of new stuff again. Hopefully that should be different for 4.17.
Please pull.
Thanks
James

MIPS changes for 4.16
These are the main MIPS changes for 4.16. Rough overview:
- Basic support for the Ingenic JZ4770 based GCW Zero open-source handheld video game console
- Support for the Ranchu board (used by Android emulator)
- Various cleanups and misc improvements
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"
