[U-Boot] [PATCH v4 01/10] ARM: HYP/non-sec: move switch to non-sec to the last boot phase

[Marc Zyngier]

Having the switch to non-secure in the "prep" phase is causing
all kind of troubles, as that stage can be called multiple times.

Instead, move the switch to non-secure to the last possible phase,
when there is no turning back anymore.
