Jan Kiszka a8f2d01967 tegra: Boot in non-secure mode by default
Upstream Linux is broken with default configs when PSCI, thus non-secure
mode is enabled. So the user should explicitly enable this mode, e.g.
when she disabled CONFIG_CPU_IDLE in Linux (in which case it's safe to
use). We can revert this workaround once Linux got fixed.

Say Y here to boot in secure mode by default even if non-secure mode
is supported. This option is useful to boot kernels which do not
suppport booting in non-secure mode. Only set this if you need it.
This can be overriden at run-time by setting the bootm_boot_mode env.
variable to "sec" or "nonsec".

boolean "Enable support for hardware virtualization" if EXPERT

Say Y here to boot in hypervisor (HYP) mode when booting non-secure.
