Hi,
Sorry for the formatting. I am pretty sure you need to CC "THE REST" here.

IMHO, it would make sense to move this option in the arch/{arm,x86)/Kconfig.
But I am not sure how this will work as with this series you can select

Anyway, as I mention the way to go is a option list with only one possible
choice.
