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 are preparing to add LoongArch support in mainline kernel,
we can see a snapshot here:
https://github.com/loongson/linux/tree/loongarch-next

Cross-compile tool chain to build kernel:
https://github.com/loongson/build-tools/releases

Loongson and LoongArch documentations:
https://github.com/loongson/LoongArch-Documentation

ECR for LoongArch-specific interrupt controllers:
https://mantis.uefi.org/mantis/view.php?id=2203
https://mantis.uefi.org/mantis/view.php?id=2313

ACPI changes of LoongArch have been approved in the last year, but the
new version of ACPI SPEC hasn't been made public yet.

V2: Remove merged patches and update commit messages.

Huacai Chen and Jianmin Lv(2):
 ACPICA: MADT: Add LoongArch APICs support.
 ACPICA: Events: Support fixed pcie wake event.

Both patches in this series are mostly ACPICA material which needs to
be submitted to the upstream ACPICA project via
https://github.com/acpica/acpica

It will be pulled by the Linux kernel from there.

This tables.c change can be submitted as a separate patch when the
ACPICA changes get integrated.

I found that you are also a maintainer of the ACPICA project, do you
mean I should submit by github PR, not by maillist?

Do you mean split the first patch into .h parts and .c parts, then
submit the .h parts and the second patch by github PR, then submit the
.c parts of the first patch by maillist?
