Merge tag 'mips_5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS updates from Thomas Bogendoerfer:
- removed support for PNX833x alias NXT_STB22x
- included Ingenic SoC support into generic MIPS kernels
- added support for new Ingenic SoCs
- converted workaround selection to use Kconfig
- replaced old boot mem functions by memblock_*
- enabled COP2 usage in kernel for Loongson64 to make use
of 16byte load/stores possible
- cleanups and fixes
