What about the following solution:


arch/powerpc/Kconfig.qe:

<--  snip  -->

config MACH_SUPPORTS_QE
	bool

config QE
	bool "QUICC Engine Support"
	depends on MACH_SUPPORTS_QE
	help
	  ...

<--  snip  -->


arch/powerpc/platforms/83xx/Kconfig:

<--  snip  -->

...
source arch/powerpc/Kconfig.qe

config PPC_MPC836x
        bool
	select MACH_SUPPORTS_QE
	...
....

<--  snip  -->
