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.
