I understand where your coming from, but the problem is that
CONFIG_ARMV7_SEC_BY_DEFAULT as a Kconfig option should depend on
CONFIG_ARMV7_VIRT or CONFIG_ARMV7_NONSEC, which depend on
CONFIG_ARMV7_PSCI / CONFIG_ARMV7_PSCI_NR_CPUS and
CONFIG_ARMV7_SECURE_BASE, all of which are currently set
through include/configs/foo.h.

I know that the plan is to move all of these to Kconfig eventually,
but there still is a lot of figuring out how that exactly should be
done, and as such I believe that it is best to set
CONFIG_ARMV7_SEC_BY_DEFAULT the "old-fashioned" way for now.

Hans
