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
