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'" * tag 'mips_4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips: (53 commits) MIPS: Malta: Sanitize mouse and keyboard configuration. MIPS: Update defconfigs after previous patch. MIPS: Push ARCH_MIGHT_HAVE_PC_SERIO down to platform level MIPS: Push ARCH_MIGHT_HAVE_PC_PARPORT down to platform level MIPS: SMP-CPS: Remove duplicate assignment of core in play_dead MIPS: Generic: Support GIC in EIC mode MIPS: generic: Fix Makefile alignment MIPS: generic: Fix ranchu_of_match[] termination MIPS: generic: Fix machine compatible matching MIPS: Loongson fix name confict - MEM_RESERVED MIPS: bcm47xx: enable ZBOOT support MIPS: Fix trailing semicolon MIPS: Watch: Avoid duplication of bits in mips_read_watch_registers MIPS: Watch: Avoid duplication of bits in mips_install_watch_registers. MIPS: MSA: Update helpers to use new asm macros MIPS: XPA: Standardise readx/writex accessors MIPS: XPA: Allow use of $0 (zero) to MTHC0 MIPS: XPA: Use XPA instructions in assembly MIPS: VZ: Pass GC0 register names in $n format MIPS: VZ: Update helpers to use new asm macros ...
