Since more and more arm chips support device tree, it'd be better add
PROC_DEVICETREE
in arch/arm/Kconfig to avoid duplicate code.

I think this should remain user choice. If its going to be selected,
then you might as well just remove the option altogether. Perhaps just
make the option default to yes.

Hmm, sounds reasonable from your point. So the better choice is to set the
option default to Y if the board has dt support just like tegra_defconfig
and at91_dt_defconfig,  right? thanks.

Why bother? If the defconfigs select it then most users basing their
config from that will be just fine.

PROC_DEVICETREE is 100% optional, it's useful to get runtime access to
the contents of the device tree but it's not required for the kernel
to boot.
