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
