How about both? Other users of early_param_on_off() set the default
state using kconfig. Is that an acceptable choice, or should I remove
the command line parameter all together? I sort of expect that in a few
years time, the whole option goes away once it been in use for a while
and there are a number of V8 implementations widely available.
