  MAINTAINERS: Add maintainer information for LoongArch (2022-06-03
20:09:29 +0800)

[ Side note: All the contents in this branch look fine to me and I think we are
 better off with them in 5.19 than later, mainly because it allows merging the
 glibc port sooner. On the other hand, the way here has been somewhat irregular
 and rushed, and as explained in the tag it doesn't  actually boot. If
you have any
 doubts about the submission, it can obviously wait for another release and get
 done properly then. - Arnd ]

Add partial Loongarch architecture code

This is the majority of the loongarch architecture code, including
the final system call interface and all core functionality.

It still misses three sets of peripheral but vital patches to add
support for other subsystems, which have yet to pass review:

 - The drivers/firmware/efi stub for booting from a standard UEFI
   firmware implementation. Both the original custom boot interface
   and a draft implementation of the EFI stub did not make it, so
   it is currently impossible to boot the kernel, until the
   loongarch specific portions get accepted into the UEFI subsystem

 - The drivers/irqchip/irq-loongson-*.c drivers are shared with the
   MIPS port, but currently lack support for ACPI based booting,
   which will get merged through the irqchip subsystem.

 - Similarly, the drivers/pci/controller/pci-loongson.c needs to be
   modified for ACPI support, which will be merged through the
   PCI subsystem.

While the port cannot actually be used before all the above are
merged, having it in 5.19 helps to establish the user space ABI
for the libc ports to build on, and to help any treewide changes
in the mainline kernel get applied here as well. A gcc-12 based
tool chains for build testing is now included in
https://mirrors.edge.kernel.org/pub/tools/crosstool/.

Original description from Huacai Chen at
https://lore.kernel.org/lkml/20220603072053.35005-1-chenhuacai@xxxxxxxxxxx/:

 "LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.
  LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit
  version (LA32S) and a 64-bit version (LA64). LoongArch use ACPI as its
  boot protocol LoongArch-specific interrupt controllers (similar to APIC)
  are already added in the next revision of ACPI Specification (current
  revision is 6.4).

  This patchset is adding basic LoongArch support in mainline kernel, we
  can see a complete snapshot here:
