That is you mean to re-use it for RISC-V?
Yes, I will re-use it.

This then would better be converted to "depends on HAVE_DOM0LESS", which
for now only Arm would select. With a dependency on XYZ the default also
doesn't need to name XYZ again, i.e. can simply be "default y".
"depends on HAVE_DOM0LESS" would be better. I will update correspondingly.

Thanks.
