[FFmpeg-devel] [PATCH 0/3] MIPS MSA & MMI Runtime detection support

[Jiaxun Yang]

This series adds MIPS MSA & MMI runtime detection support.

It have been tested on Loongson-3A4000 (with both MSA & MMI),
Loongson-3B1500 (MMI only), MT7620A (no SIMD ASE).

There is a MMI checkasm test failure but looks irrelevant with my changes,
I have informed MIPS maintainer Shiyou Yin privately and he said he'll take
a look.
