Merge tag 'mips_4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS updates from Paul Burton:
- kexec support for the generic MIPS platform when running on a CPU
including the MIPS Coherence Manager & related hardware.
- Improvements to the definition of memory barriers used around MMIO
accesses, and fixes in their use.
- Switch to CONFIG_NO_BOOTMEM from Mike Rapoport, finally dropping
reliance on the old bootmem code.
- A number of fixes & improvements for Loongson 3 systems.
- DT & config updates for the Microsemi Ocelot platform.
- Workaround to enable USB power on the Netgear WNDR3400v3.
- Various cleanups & fixes.
