Subject: [PATCH 27/36] ARM: HYP/non-sec: move switch to non-sec to the last
|
|
boot phase
|
|
|
|
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.
|
|
