Merge tag 'mips_5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux

Pull MIPS updates from Paul Burton:
 "The main MIPS changes for 5.5:

   - Atomics-related code sees some rework & cleanup, most notably
     allowing Loongson LL/SC errata workarounds to be more bulletproof &
     their correctness to be checked at build time.

   - Command line setup code is simplified somewhat, resolving various
     corner cases.

   - MIPS kernels can now be built with kcov code coverage support.

   - We can now build with CONFIG_FORTIFY_SOURCE=y.

   - Miscellaneous cleanups.

  And some platform specific changes:

   - We now disable some broken TLB functionality on certain Ingenic
     systems, and JZ4780 systems gain some devicetree nodes to support
     more devices.

   - Loongson support sees a number of cleanups, and we gain initial
     support for Loongson 3A R4 systems.

   - We gain support for MediaTek MT7688-based GARDENA Smart Gateway
     systems.

   - SGI IP27 (Origin 2*) see a number of fixes, cleanups &
     simplifications.

   - SGI IP30 (Octane) systems are now supported"
