What's the point of selecting it if it's always "y"?
That's because on X86 is not always "y": there are things under drivers/xen that compile on both platforms and depend on XEN_DOM0.
But we're not on x86. On ARM this select is pointless.
We need some common code (under drivers/xen) that compiles only if XEN_DOM0 is selected, so it is not pointless after all.
XEN_DOM0 is not the only symbol that is conditionally compiled on one architectuire and always "y" on another...
Wait a sec, I have just realized that written this way XEN_DOM0 is always "y", even if XEN is not! The right way of doing this is:
config XEN_DOM0 def_bool y depends on XEN
config XEN bool "Xen guest support on ARM (EXPERIMENTAL)" depends on EXPERIMENTAL && ARM && OF help Say Y if you want to run Linux in a Virtual Machine on Xen on ARM.
I am not sure if this is what you meant, but thanks for making me realize this mistake anyway! :)
