Is there any reason why CPU_FEROCEON is not listed here? FWIW, I've just built
(but not really tested) a Kirkwood kernel with CONFIG_HIBERNATION=y.

And is there any reason to put this config in arch/arm/mm/Kconfig, instead of
in arch/arm/Kconfig, below ARCH_SUSPEND_POSSIBLE? 

I'm also puzzled about having two separate options for suspend and hibernate,
maybe someone can explain me why a given CPU would support the former but not
the latter?

Thanks!
