I can tell, LoongArch has no UP system.
arm64 crossed that bridge a long time ago, and we never looked
back, because these systems hardly exist.
I'd rather you simply have a CONFIG_SMP always set to 'y', and
be done with it forever.
haven't translate all documents at
https://loongson.github.io/LoongArch-Documentation/ in time, there are
currently 4 LoongArch64 processors: Loongson-2K500 (single-core),
Loongon-2K1000 (dual-core), Loongson-3A5000 (quad-core) and
Loongson-3C5000 (16-core). So we indeed need a UP configuration.
Thanks.
