At the same time, you need to modify the loongarch in arch-support.txt
to ok.
BTW, we can submit a separate patch to modify the features already
supported by LoongArch.
The following features are already supported in LoongArch.

Thank you, I have already prepared a patch to update the docs,
but some more features will be added on LoongArch in the following
merge window, I am not sure what is the proper time to send the
following patch, maybe two months later, or right away, maybe
Jonathan can give some suggestions.
Documentation/features: Refresh LoongArch support files
Run the refresh script [1] to document the recent feature additions
on LoongArch.
[1] Documentation/features/scripts/features-refresh.sh
Thanks,
Tiezhu
