Well, my goal is to eliminate drivers/of/, but no.

Which architecture needs this code? Do we wait and see who complains 
their platform broke and then go set this option? In the meantime, new 
platforms started depending on the new behavior and setting the option 
may break them. So we can't have a kconfig option.

Per platform code handling the cmdline is completely the wrong 
direction. Per arch behavior is bad enough.
