The new Kconfig options have "default y", and the boards where using
those settings before.

Or are you referring to the fact that CONFIG_ARMV7_NONSEC is getting
set for arndale and vexpress_ca15_tc2 now too ? That is intentional
ARMV7_VIRT depends on CONFIG_ARMV7_NONSEC.

So far this has been somewhat unelegantly solved by writing every
#ifdef CONFIG_ARMV7_NONSEC as:

#if defined(CONFIG_ARMV7_NONSEC) || defined(CONFIG_ARMV7_VIRT)

So that setting CONFIG_ARMV7_VIRT automatically also includes all the
NONSEC bits, note that after this patch we could simply these to just:

#ifdef CONFIG_ARMV7_NONSEC

Which would also more correctly reflect when the code should be enabled.
