Well, I'm not sure, but I would not bet either...

I know for sure that some people are using Buildroot to build small
systems that they use as docker roots for example (they've spoken so
either on the list or on the IRC channel some time ago). Those are
mostly expected to run on server-class machines. The Thunder familly
of CPUs are just meant for those kind of server-class machines.

So I do see a direct use-case for adding the ThunderX familly of cores,
yes.

For the others, I'm not as positive, but I still added them while I was
at it. Not much additional work, except waiting for more tests to run...
;-)

Regards,
Yann E. MORIN.
