Some platforms may use a single device tree to describe two address
spaces, as described in d9f43babb998 ("Documentation: dt: Add bindings
for Secure-only devices"). We extend the use of the secure- prefix to
the stdout-path property, so that the Secure firmware may use a
different console device than the one used by the kernel.
