REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4054

The uploaded code generates firmware to support Linux launching on the 
LoongArch platform under qemu,
So it will run in a virtual machine.

LoongArch is the general processor architecture of Loongson.
You can get the latest LoongArch documents or LoongArch tools at 
https://github.com/loongson/.

You can also view the code through the Loongson community.
