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'"
