When can support LoongArch cpu?

I use the loongsonA5000 cpu.When can support it?

Apparently, Loongson is MIPS64. MIPS64 is already a Tier 2 target.

I see that you posted the same question on internals.rust-lang.org as well. When you do this, please include cross-links in each post, so that the discussions aren't completely siloed. (Generally we prefer you not post the same question on both URLO and IRLO anyway.)
