Maybe Troy Mitchell from Spacemit can shed light on this question.

Anyway, I could use the same wording as in this commit introducing 
"OrangePi RV2":
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch?id=bab8dea259100a99e047fd11a48940b229d30031

"The board is described as using the Ky X1 SoC, which, based on 
available downstream sources and testing, appears to be identical or 
very closely related to the SpacemiT K1 SoC".

What do you think?

Cheers,
Michael
