This will always be 'n'.

And clk-generated.o will never be built.

I think your options are to use
	config HAVE_AT91_GENERATED
		def_bool y

or
	config HAVE_AT91_GENERATED
		bool "Yadda yadda yadda"

or add
	select HAVE_AT91_GENERATED

somewhere (possibly even in a second patch). But as it stands the patch
looks like an elaborate NOP.

Thanks,
