On ARM and MIPS, this is called 'config USE_OF'.  It would be nice to have
some commonality.  Maybe I should move the user-visible option to
drivers/of/Kconfig.  Or perhaps I should just make CONFIG_OF itself
user visible.

thoughts?

We could make CONFIG_OF depend on CONFIG_HAVE_OF_SUPPORT and let OF
select OF_EARLY_FLATTREE if ARCH_WANT_EARLY_FLATTREE for instance. So
that part would work in a generic way.

For OF-only platforms you would have to go to drivers/of
before you can enable the specific SoC/board. So it could lead to
something like "first enable scsi disk before you can enable usb
storage".

That's definitely not desirable.  Currently ARM and MIPS boards that
need it are force-selecting USE_OF which pretty much solves the
problem.  The option is always user-

I like it :) For now I rename to USE_OF.

okay.
